have separate configuration spaces so by definition they implement different PCI domains. Thus change psycho(4) to use PCI domains instead of reenumerating all PCI busses so they have globally unique bus numbers and drop support for reenumerating busses in the OFW PCI code. According to CVS history reenumeration was also required in order to get some E450 to boot but given that no other open source kernel changes the PCI bus numbers assigned by the firmware I believe the real problem was that the old code used the bus number as the device number for the PCI busses and unlike most of the other machines the firmwares of the problematic ones don't use disjoint PCI bus numbers across the host-PCI-bridges.
