I had the same problem here (except that it was a
DViCO FusionHDTV5 Lite loading bttv instead of a bt8x8
card), and I fixed it by adding the line "blacklist
bttv" to /etc/modprobe.d/blacklist.

The ivtv driver ends up loading bttv as part of it, so
it all works out for me.  I'm not sure that this is
kosher, but it's working for me thus far.
