It'd also be nice to handle hotplug PCI nicely at the same time..
e.g. there should be a facility to register a "listener" for a given
PCI type.. and first all matching existing devices would call the handler
callback, and then any device inserted would trigger it..
preferably one would do this without re-autoprobing-- e.g. keep hash
tables of what hardware is in the system.
