Ryan,
I had the exact same problem a few months ago. I thought I had posted the
resolution to this list but it was actually the linux-abit list.
The important bits of information that solved the problem for me were:
1) the bt878 will not share an IRQ
2) PCI slots 4 and 5 cannot *both* have a bus-mastering card in them
(rule of thumb is to leave one of them empty)
here is an excerpt from my linux-abit post (note that I am running
dual-headed with both an AGP and PCI video card):
I found a combination of cards and slots that works!
1. FA310TX NIC
2. BT878 TV card
3. PCI TNT
4. empty
5. es1371 sound

the PCI TNT card is on IRQ 10 but does not show up above
