Ah, I introduced a mechanism for doing the opposite of this in 2.6-test8 (it's credited to Ben Herrenschmidt since he did the debugging and got it merged). If you call insert_resource() instead of request_resource(), conflicting resources get the new resource added as their parent. I knew this was going to be handy for more than just PPC ;-) -- "It's not Hollywood. War is real, war is primarily not about defeat or victory, it is about death.
