I think that could be handled with pcibios_root_bridge_prepare() or
something similar -- something that happens in the "add host bridge"
path. I'm not saying we necessarily have all the right hooks in place
yet. It's just that I'd rather figure out what the right hooks *are*
and add them if necessary, than just convert pci_root_buses to
for_each_pci_host_bridge().

I think it's really the acpiphp/pciehp issue that's holding up the
removal of acpi_pci_driver. I'm not sure if anybody's working on
that.
