Hi folks,
as an addition to Edgar's 6 patches the following stuff are my documentation
fixes.
I publish them here as they are in Mercurial and in the mm-branch, but still
not
where they should be: in the main kernel tree at kernel.org.
Hope this stuff helps in answering questions too.
Also hope it doesn´t get wordwrapped by some email client.

1. bt8xx.txt
- reduce the core information to the necessary minimum
- avoid hexadecimal card IDs as not being necessary
- sync the mentioned card list to the standards in bttv.h
- reformatting of the whole structure
applies against kernel: 2.6.16

-require the bttv driver.

+1) General information
+======================
 
-These drivers require the bttv driver to provide the means to access
-the i2c bus and the gpio pins of the bt8xx chipset.
-
-Because of this, you need to enable
-"Device drivers" => "Multimedia devices"
-  => "Video For Linux" => "BT848 Video For Linux"
-
-Furthermore you need to enable
-"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting
Devices"

 2) Loading Modules
 ==================
 
-In general you need to load the bttv driver, which will handle the gpio and
-i2c communication for us, plus the common dvb-bt8xx device driver.
-The frontends for Nebula (nxt6000), Pinnacle PCTV (cx24110), TwinHan (dst),
-FusionHDTV DVB-T Lite (mt352) and FusionHDTV5 Lite (lgdt330x) are loaded
-automatically by the dvb-bt8xx device driver.
+In default cases bttv is loaded automatically.
+To load the backend either place dvb-bt8xx in etc/modules, or apply
manually:
+
+    $ modprobe dvb-bt8xx
+
+All frontends will be loaded automatically.
+People running udev please see Documentation/dvb/udev.txt.
+
+In the following cases overriding the PCI type detection for dvb-bt8xx
might be necessary:
 
-3a) Nebula / Pinnacle PCTV / FusionHDTV Lite
----------------------------------------------
-
-   $ modprobe bttv (normally bttv is being loaded automatically by kmod)
-   $ modprobe dvb-bt8xx
-
-(or just place dvb-bt8xx in /etc/modules for automatic loading)
-
-
-3b) TwinHan and Clones
---------------------------
+2a) Running TwinHan and Clones
+------------------------------
 
-   $ modprobe bttv card=0x71
-   $ modprobe dvb-bt8xx
-   $ modprobe dst
+    $ modprobe bttv card=113
+    $ modprobe dvb-bt8xx
+    $ modprobe dst
 
-The value 0x71 will override the PCI type detection for dvb-bt8xx,
-which  is necessary for TwinHan cards. Omission of this parameter might
result
-in a system lockup.
-
-If you're having an older card (blue color PCB) and card=0x71 locks up
-your machine, try using 0x68, too. If that does not work, ask on the
-mailing list.
-
-The DST module takes a couple of useful parameters.
-
-verbose takes values 0 to 4. These values control the verbosity level,
-and can be used to debug also.
-
-verbose=0 means complete disabling of messages
-    1 only error messages are displayed
-    2 notifications are also displayed
-    3 informational messages are also displayed
-    4 debug setting
-
-dst_addons takes values 0 and 0x20. A value of 0 means it is a FTA card.
-0x20 means it has a Conditional Access slot.
-
-The autodetected values are determined by the cards 'response string'
-which you can see in your logs e.g.
-
-dst_get_device_id: Recognise [DSTMCI]
-
-If you need to sent in bug reports on the dst, please do send in a complete
-log with the verbose=4 module parameter. For general usage, the default
setting
-of verbose=1 is ideal.
-
-
+Useful parameters for verbosity level and debugging the dst module:
+
+verbose=0:        messages are disabled
+    1:        only error messages are displayed
+    2:        notifications are displayed
+    3:        other useful messages are displayed
+    4:        debug setting
+dst_addons=0:        card is a free to air (FTA) card only
+       0x20:    card has a conditional access slot for scrambled channels
+
+The autodetected values are determined by the cards' "response string".
+In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
+For bug reports please send in a complete log with verbose=4 activated.
+Please also see Documentation/dvb/ci.txt.
-4) Multiple cards
---------------------------
-
-If you happen to be running multiple cards, it would be advisable to load
-the bttv module with the card id. This would help to solve any module
loading
-problems that you might face.
-
-For example, if you have a Twinhan and Clones card along with a FusionHDTV5
Lite
-
-    $ modprobe bttv card=0x71 card=0x87
-
-Here the order of the card id is important and should be the same as that
of the
-physical order of the cards. Here card=0x71 represents the Twinhan and
clones
-and card=0x87 represents Fusion HDTV5 Lite. These arguments can also be
-specified in decimal, rather than hex:
-
-    $ modprobe bttv card=113 card=135
-
-Some examples of card-id's
-
-Pinnacle Sat        0x5e  (94)
-Nebula Digi TV        0x68  (104)
-PC HDTV            0x70  (112)
-Twinhan            0x71  (113)
-FusionHDTV DVB-T Lite    0x80  (128)
-FusionHDTV5 Lite    0x87  (135)
 
+2b) Running multiple cards
+--------------------------
+
+Examples of card ID's:
+
+Pinnacle PCTV Sat:         94
+Nebula Electronics Digi TV:    104
+pcHDTV HD-2000 TV:        112
+Twinhan DST and clones:     113
+Avermedia AverTV DVB-T 771:    123
+Avermedia AverTV DVB-T 761:    124
+DViCO FusionHDTV DVB-T Lite:    128
+DViCO FusionHDTV 5 Lite:    135
+
+Notice: The order of the card ID should be uprising:
+Example:
+    $ modprobe bttv card=113 card=135
+    $ modprobe dvb-bt8xx
+
-For a full list of card-id's, see the V4L Documentation within the kernel
-source:  linux/Documentation/video4linux/CARDLIST.bttv
-
-If you have problems with this please do ask on the mailing list.
+For a full list of card ID's please see
Documentation/video4linux/CARDLIST.bttv.
+In case of further problems send questions to the mailing list:
