Just week or so ago someone reported that the 771 works with "Gentoo's
latest 2.6.12 with the 2.6.12 patches from the linuxtv.org download site":
http://linuxtv.org/pipermail/linux-dvb/2005-July/003777.html

The patches haven't changed since then, so maybe it's something
in Gentoo's kernel? Maybe you might want to try plain 2.6.13-rc6,
or diff dvb-bt8xx.c, bttv-i2c.c and bttv-cards.c with versions
from the last kernel which worked for you. If the card just
stopped working without you changing the driver/kernel then
it's probably just dying. Or maybe a heat problem? Or flaky
power supply?
