Works for me, 2.6.10-rc1.

My etc/rc.boot/local includes:

# video stuff
modprobe dvb_bt8xx
modprobe v4l1-compat
# Avermedia DVB-T (761)
modprobe sp887x
# Avermedia DVB-T 771
modprobe mt352

And /var/log/messages shows:

Now that I think of it, I did apply some extra patches that were on the list
late Oct.
	2.6.10-rc1-01-dvb-av7110-debug.patch
	2.6.10-rc1-02-dvb-misc.patch
	2.6.10-rc1-03-dvb-add-cinergy-t2.patch
	2.6.10-rc1-04-dvb-dibusb-update.patch
	2.6.10-rc1-05-dvb-frontend-update.patch

And a tiny one later:

                 }
                 kfree(map);
         }

I am now building vanilla -rc2 which has many v4l fixes.

Good luck.
