I've got problems too with a Hauppage Nova-T (SAA7146 chipset). Kudzu 
doesn't pick it up.

The kernel 2.6.7 is supposed to fix some of those issues but the 
Changelog is pretty scary:

<hunold@convergence.de>
	[PATCH] Make tda1004x DVB frontend driver work again
	
	Adrian Bunk noticed that the tda1004x DVB frontend driver was
        broken and sent a small patch that at least made the driver
        work again.
	
	There was a discussion afterwards about the kernel syscall
        interface, but at the end, the tda1004x DVB frontend driver is
        still non-functional.
	
	This re-applies the temporary band-aid.

I *think* this tda1004x.c file is what gets those DVB cards working. In 
the kernel source there is this comment in this file:


*
    This driver needs a copy of the DLL "ttlcdacc.dll" from the Haupauge
    or Technotrend windows driver saved as
    '/usr/lib/hotplug/firmware/tda1004x.bin'.
    You can also pass the complete file name with the module parameter
    'tda1004x_firmware'.

    Currently the DLL from v2.15a of the technotrend driver is
    supported. Other versions can be added reasonably painlessly.

I found the driver on my windoze CD-ROM install - I've no idea if it's 
the right version though.

So I installed the new-ish kernel with its source with apt, rebooted, 
re-compiled the Nvida kernels against the new kernel, started X and... 
nothing. It all froze up during X init and rebooted after a while, 
probably because I was bashing my keyboard with rage :-)

Also, even with the new kernel and the firmware installed where it 
should be, kudzu does not pick up the card at startup.

I might try to re-compile a 2.6.6 kernel with the patch from 2.6.7, but 
right now it seems pretty hopeless to me... I'm such a luser - "It don't 
work" :-)

(Besides, browsing the MythTV archives, apparently it's a mess to set up 
with digital terrestrial. Doh.)
