I think the proper fix in the long run is to make the isa bridge
handling code in pci-64 common, but that's going to be after I rework
the IO space allocation/mapping mechanisms for pci-32 to also look like
pci-64 so it will take a little while.

In the meantime, I agree, just leave it to NULL, we can do a better
fixup on top of that. As it is, it's going to hurt Pegasos too (the
other 5 users :-)

Cheers,
Ben.
