that mirror is not complete, but as you can read there with a recent
mercurial get_dvb_firmware you can try to get latest revision 29 from
But first of all you must change the mentioned line of code to force
loading from file instead from eeprom, like my older revision of the

See above, but yes, difficult to know what exactly happens, since useful
stuff like "udevmonitor" doesn't help either.

For now with the above modification card=78 seems fine, but for example
still no report for radio function. Either the card should have its own
entry ASAP or we would at least need some sort of detection and switch
case in saa7134-dvb for the firmware loading.

2.6.18-rc7 should be sufficient. There are two patches floating out of
The remote patch is untested on 1043:4876 and needs some more cleaning.
In longer terms likely reorganization to share it with the other drivers
(most comes from bttv-input.c RC5) to avoid duplicate code. Depending on
kernel/driver version probably needs to be applied manually.
Currently rc5_key_timeout=50 is recommended or change it in the code.

Definitely yes. Check the video4linux-list at redhat.com.
