This will only add bridges for the explictly mentioned buses, which
would mean we could have buses 0 and 6 with no buses between them.
Maybe we should add them the way we add disk controllers - find the
highest index and add all bridges with indexes from 1 to max.

It would be nice if we could add pci bridges even when there weren't any
specified in the XML, but there are too many PCI devices. I don't know
what would be the nicest way to do that. Maybe Peter's patches for
config parser defaults will be helpful:
