Firewire doesn't work after upgrading motherboard

I had firewire working (able to access external HD and CDRW drives)
with my old motherboard, an ASUS A7S333 (SiS 745 chipset). I replaced
the motherboard with a Gigabyte 7VT600 (Via KT600 chipset), and I can
no longer user firewire. In the process, I did have to completely
reinstall the OS, but I'm pretty sure I did everything firewire
needed.

I've tried 2.4.21 (what I had on the old motherboard) and 2.4.22.

Here's the output of dmesg (2.4.21) from loading the modules:
    ieee1394: Host removed: Node[00:1023] GUID[00601d0000000037] [Linux

gscanbus doesn't run. It starts up with a bunch of garbage in its
window, and writes the following output:
    Error while reading from IEEE1394: : Resource temporarily unavailable
    something is wrong here
    Error while reading from IEEE1394: : Resource temporarily unavailable

What am I doing wrong?

Thanks for the help.
