Funny you should mention that. I am in fact playing the pc104 game, with
the sensoray 311. I actually just noticed the comment in bttv-cards.c
and was about to email you for help! :)

Anyways, I had fiddled with different jumper settings on jp5-8, and from
what I knew of pci interrupts, jp5 should be the correct setting. Except
for one little thing - with jp5 on, the kernel hangs right after
"i2c-core.o: adapter bt848 #0 registered as adapter 0."

So yes, jp5 should resolve my irq timeout problem, but you don't happen
to have any experience with it freezing the kernel on driver load do
you? I have jp3 a and b on, so it's set to module slot 0. i have no idea
what the lone jumper next to the isa connector, labelled jp2 does (it's
open), do you?
