I appear to be seeing something like this with panther2.freebsd.org.
Booting GENERIC with boot -v gives:

[...]
pcib2: <APB PCI-PCI bridge> at device 1.0 on pci0
pcib2:   secondary bus     2
pcib2:   subordinate bus   2
pcib2:   I/O decode        0x0-0x1fffff, 0x200000-0x3fffff, 0x400000-0x5fffff, 0x600000-0x7fffff, 0x800000-0x9fffff, 0xa00000-0xbfffff

pci2: <OFW PCI bus> on pcib2
pci2: physical bus=2
procfs registered
Timecounters tick every 10.000 msec
lo0: bpf attached
[hangs]
