So it seems like the XIO2000(A) is being misconfigured or  
misidentified, and rather than finding the configured bus behind  
the bridge, it is doing "something else", and as a result, not  
finding the PCI OHCI FireWire controller on the PCI side of the  
bridge.

Unfortunately I have no real idea where to start looking at this...

Any ideas? Or is there a better place to be posting about this?

This is a reasonable place to post this.  Can you see what u-boot  
reports for its PCI/e bus scan?

Thanks,

This is what u-boot says:

If there is additional information to be found, I'd be happy to  
collect it.
