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?
