Ah, now I see "pchb at pci" on i386 actually attaches another
PCI bus (AGP), but in this case the pchb belongs to the primary
PCI bus so "pci at pchb" is not problematic.
(though I doubt ibmnws and pmppc could have such bus)
On the other hand, "pchb at non-pci" is still confusing and
currently only ibm4xx ports in evbppc have such one.
