Well, what about have one central device "/dev/hotplug". When device
is plugged, one byte comes out of it. Everyone who cares (X, etc)
opens /dev/hotplug. When _anything_ comes, everyone wakes up, and
looks if something interesting came.
That is much cheaper than polling -- how ofter do you add devices to
your system -- and it should be easy enough to do.
