IMO we should start by using the new notifier chain and by implementing
a central "icebox" routine. Then we can forbid device registration
during suspend.

It might also be a good idea to add a freezable keventd-like workqueue
specifically intended for things that need to block during a suspend.
Although maybe this will end up being unnecessary; it's too soon to
tell.
