I've just finished my new attempt, starting again from scratch, mostly
following advice from Vincenzo Di Massa and Michael Hunold.

This is what I did:

1. Unpacked 2.4.23 kernel, configured with video4linux, i2c, etc.
2. Build kernel & modules & installed both
3. cvs co dvb-kernel
4. ran getlinks script in dvb-kernel
5. make in dvb-kernel/build-2.4
6. install in dvb-kernel/build-2.4
7. Booted up the new 2.4.23 TV kernel
8. Run dvb-nebula script to start modules.

BTW, I assume you don't have to be running the new kernel when you
"make install" in dvb-kernel/build-2.4?  I.e., steps 5 & 6 can be done
before step 7?

(It's also possible that Vincenzo meant I should also do the extra steps
of unpacking bttv and patching it, and getting video4linux (2) and
making and installing that too.  But I did not unpack, build and install
video4linux-20031201.tar.gz - I just relied on what was in the released
2.4.23 kernel.)

I also get this error from "make install" in dvb-kernel/build-2.4
depmod: *** Unresolved symbols in /lib/modules/2.4.23-tv/misc/dvb-bt8xx.o


# ./dvb-nebula start
Inserting DVB modules into kernel./dvb-nebula: line 41:  1773 Segmentation fault
      modprobe bttv

And modprobe appears to have hung, so I'll need to reboot after I send
this email.

I notice that the dvb-nebula script just does "modprobe bt878" whereas
the dvb-kernel/build-2.4/insmod-bt8xx.sh script says:

        # bttv is required for bt878 and dvb-bt8xx
        # card=0x68 is vital FOR THE DST CARD
        insmod bttv.o card=0x68 i2c_hw=1

But I figure the Nebula DigiTV card is not the DST card, so the
dvb-nebula script should probably be okay if you have the Nebula card. 
I think they're different cards since video4linux-20031201/doc/CARDLIST.bttv
says:

	card=104 - Nebula Electronics DigiTV
	...
	card=113 - Twinhan DST + clones

But the dvb-nebula script doesn't appear to pass the card parameter (I
note that 104 = 0x68).  Does that matter?  If such a parameter is
needed for the modprobe, I think it would have to be added to
/etc/modules.conf, wouldn't it?

Anyway, I ran this:

ksymoops -v /usr/src/linux-2.4.23/vmlinux -m /boot/System.map-2.4.23 \
     -o /lib/modules/2.4.23 segfault3

But I'm puzzled by the ksymoops warning messages like:

ksyms_base symbol GPLONLY___ide_do_rw_disk not found in vmlinux.
  Ignoring ksyms_base entry
mismatch on symbol bt878  , bt878 says d096ca20, /lib/modules/2.4.23/misc/bt878.o
 says d096c980.  Ignoring /lib/modules/2.4.23/misc/bt878.o entry

It's a fresh kernel and fresh modules and the symbols should all match.
In dvb-kernel/build-2.4 the "make install" did give the eror at the end:
depmod: *** Unresolved symbols in /lib/modules/2.4.23/misc/dvb-bt8xx.o

I have two /lib/modules/2.4.23 module sets I created today, both from
the fresh 2.4.23 kernel.  One I've now called 2.4.23-tv-depmod-okay
and the other is 2.4.23-tv.  I don't know how I made the -depmod-okay
one, but it's the only one that avoids the unresolved symbols error
message.  The two directories differ in these files:

# diff -qr 2.4.23-tv 2.4.23-tv-depmod-okay
Only in 2.4.23-tv: misc
Files 2.4.23-tv/modules.dep and 2.4.23-tv-depmod-okay/modules.dep differ
Files 2.4.23-tv/modules.pcimap and 2.4.23-tv-depmod-okay/modules.pcimap differ
Files 2.4.23-tv/modules.usbmap and 2.4.23-tv-depmod-okay/modules.usbmap differ

The significant differences are:

In the modules.dep file, the 2.4.23-tv/modules.dep file has about 90 extra
lines of dependencies, like:

/lib/modules/2.4.23-tv/misc/alps_tdlb7.o:     /lib/modules/2.4.23-tv/misc/dvb-core.o

/lib/modules/2.4.23-tv/misc/alps_tdmb7.o:     /lib/modules/2.4.23-tv/misc/dvb-core.o

/lib/modules/2.4.23-tv/misc/at76c651.o:       /lib/modules/2.4.23-tv/misc/dvb-core.o

/lib/modules/2.4.23-tv/misc/bt878.o:  /lib/modules/2.4.23-tv/kernel/drivers/media/video/bttv.o

/lib/modules/2.4.23-tv/misc/cx24110.o:        /lib/modules/2.4.23-tv/misc/dvb-core.o

/lib/modules/2.4.23-tv/misc/dst.o:    /lib/modules/2.4.23-tv/misc/dvb-core.o \
      /lib/modules/2.4.23-tv/misc/bt878.o

/lib/modules/2.4.23-tv/misc/dvb-bt8xx.o:      /lib/modules/2.4.23-tv/misc/bt878.o \
      /lib/modules/2.4.23-tv/misc/dvb-core.o \
      /lib/modules/2.4.23-tv/kernel/drivers/i2c/i2c-core.o \
      /lib/modules/2.4.23-tv/kernel/drivers/media/video/bttv.o

and also the modules.pcimap files differ - the 2.4.23-tv one has extra lines
like:

diff -r 2.4.23-tv/modules.pcimap 2.4.23-tv-depmod-okay/modules.pcimap
414,437d413
< bt878                0x0000109e 0x00000878 0xffffffff 0xffffffff 0x00000000 0x
00000000 0x00000000
< dvb-ttpci-budget-av  0x00001131 0x00007146 0x00001131 0x00004f56 0x00000000 0x
00000000 0x000024ec

And the modules.usbmap also has extra lines in the 2.4.23-tv directory,
like:

diff -r 2.4.23-tv/modules.usbmap 2.4.23-tv-depmod-okay/modules.usbmap
588,592d587
< dvb-ttusb-budget     0x0003      0x0b48   0x1003    0x0000       0x0000       
0x00         0x00            0x00            0x00            0x00               
0x00               0x00000000
< dvb-ttusb-budget     0x0003      0x0b48   0x1004    0x0000       0x0000       
0x00         0x00            0x00            0x00            0x00               
0x00               0x00000000

So the /lib/modules/2.4.23-tv-depmod-okay modules directory, which
*doesn't* give the 
depmod: *** Unresolved symbols in /lib/modules/2.4.23-tv/misc/dvb-bt8xx.o
error, is the one with extra symbols ...

I've been trying to figure this out, by taking copies of the directory
and trying make install in dvb-kernel/build-2.4.  *Now* I'm in the
situation where *none* of the /lib/modules/2.4.23* directories work
with depmod, I always get the unresolved symbols error.

I see that now they all contain the "misc" directory.  Let's see, if I
remove the misc directory does the unresolved symbols message vanish
....?  Yes.  And if I put the directory back, the error comes back.

Is there any way to get a list of *what* symbols are unresolved, from
depmod?  I couldn't see any way, from reading the man page.

BTW, the misc directory contains these files:

alps_tdlb7.o  dvb-ttpci-budget-av.o     grundig_29504-491.o  tda1004x.o
alps_tdmb7.o  dvb-ttpci-budget-ci.o     mt312.o              ttpci-eeprom.o

dvb-bt8xx.o   dvb_dummy_fe.o            sp887x.o             ves1x93.o
dvb-core.o    grundig_29504-401.o       stv0299.o            video-buf.o

and seems to be created by "make install" from inside
dvb-kernel/build-2.4.  I.e., after I do that, depmod always complains
of unresolved symbols.

Anyway, FWIW, here is the /var/log/messages processed by ksymoops. 
Hope it helps:
