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.
