Yes- but maybe the locator info should be retained somewhere?

Hmm- yup. You're right. Too little sleep on my part. I think what I meant is
how you can reconcile a hardware tree (as gathered from incomplete
self-identifying h/w- OBP trees or PCI bussses, etc..) with a locator based
tree (which just tells you the attached driver hierarchy).

It may not be important to do so- but it would be nice also.
