i386/isa/pcibus.c. This gets -current running again on multiple host->pci machines after the most recent nexus commits. I had discussed this with Mike Smith, but ended up doing it slightly differently to what we discussed as it turned out cleaner this way. Mike was suggesting creating a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(), but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform property, not a quirk of a given implementation. This does use the ivar methods but does so properly. It also now prints the physical pci bus that a host->pci bridge (pcib) corresponds to.
