If you're going to do something like this, ie. true hierarchy, why not
make one tree which is "system", right? Use /proc/bus/${controllernum}
ala:

/proc/bus/0/type	--> "sbus", "pci", "zorro", etc.
/proc/bus/0/*		--> for type == "pci" ${bus}/${dev}.${fn}
			    for type == "sbus" ${slot}
			    ...

How about this?
