I think you're getting distracted from the real problem we're trying to solve here, the reason for introducing the pci_slot driver in the first place: we want to have information on all slots, not just hotplug ones. So while this is growing out of the hotplug system, we need to register all slots, even ones without _RMV. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
