The MIPS pci auto should work fine with a single PCI bus and it _should_
be a full implementation. The code was ported from PPC some time ago,
but sub busses were not tested.  Also, if I remember correctly, we
simplified a bit the more complex PPC implementation and maybe you're
seeing the result of that :)
