You might not want to hear this after spending that cash - but I've
gotten my firewire at least partially working again.  Plugreport is
reporting stuff exists at least, I haven't yet gotten to the point of
trying to capture data over it.  I mention it because I'm running the
same firewire hardware as you were - below is my lspci output.

00:00.0 Host bridge: nVidia Corporation nForce2 AGP (different
version?) (rev c1)
00:00.1 RAM memory: nVidia Corporation nForce2 Memory Controller 1 (rev c1)

And my plugreport now looks just like yours.  Also - I don't seem to
have the ieee1394 module installed.  I'm getting by with only the
following firewire-related modules loaded.

# lsmod | grep 1394
dv1394                 14420  0
ohci1394               25584  1 dv1394
raw1394                19892  0

Its on node 1.

Try the stuff over at:  http://www.mythtv.org/wiki/index.php/FireWire
I've had better luck in the past in p2p mode than broadcast - but I
think the userbase is split almost 50/50 between them as to what works
better, so experiment with both till it works.
