I hope you don't mean porting pci-auto over :)

While It was good to have back then, we should really fix out PCI layer
to properly assign unassigned devices itself.

There is much work to do to cleanup ppc32, ppc64 and core PCI so they
can deal with all the various setups around, but it's probably a
worthwhile goal.
