  FreeBSD:
    motherboard -+- pcib0 - pci0 -+- fxp0
                 |               (+- etc.)
                 |
                 +- pcib1 - pci1 -+- ahc0
                                  +- ahc1
                                 (+- etc.)


  NetBSD(with Masanori Kanaoka's patch):
    mainbus0 - pci0 -+- pchb0 - pci1 -+- pchb1 (- nothing)
                     +- fxp0          +- ahc0
                    (+- etc.)         +- ahc1
                                     (+- etc.)

 ...strange.
