You may also need to tweak pcibios_assign_bus_offset to bump it to a
higher value. There are issues when renumbering bus numbers when during
the probe, a bus is renumbered to the same number as a not-yet probed
bridge on the same segment.
That is fixed on powermac by adding an artificial "offset" of 16 between
bus numbers of different domains via this offset variable.
Ben.
