It would be nice to know exactly what it is that panics, I could well imagine that it's something like the "bus->self" that ends up being NULL for the root bus or something silly like that, simply because x86 has never needed to use these functions.
If so, it migth be as easy as just skipping buses that don't have bridge device associated with them, but this would require that you try to debug the oops a bit to figure out where it is..
Greg, do you have any PCI Express hw? Although I suspect that the pci_assign_unassigned_resources() problem probably happens on any PC, I could try it on my laptop.
