I just tried installing the Startech card on the old FIC AU13 
motherboard and it works with MythTV! Here are my outputs:

[mythtv at localhost ~]$ dmesg | fgrep firewire
firewire_ohci 0000:01:0a.0: PCI INT A -> Link[APC3] -> GSI 18 (level, 
high) -> IRQ 18

Node 1 GUID 0x001c11fffea6e812

    channel=0, data_rate=2, overhead_id=0, payload=376
iMPR n_plugs=0, data_rate=2

The GUID in MythTV autopopulated and I can watch TV.

The problem is that I was only using the FIC motherboard for testing. 
It's an old Athlon full size ATX motherboard that uses DDR memory and 
AGP video, and I just bought a MicroStar K9N6PGM2-V2 microATX DDR2 
Athlon64 motherboard with PCIe video for use with a small horizontal 
case for my home theater setup. But at least now I know how Firewire is 
supposed to work with MythTV. I suppose I will have to try some Firewire 
cards in the new MicroStar motherboard until I find one that works with
