Second part of the kldload patches for cardbus.  This makes
	kldload of a driver for a device that's inserted now appears
	to work.  To make it work, we only do a power cycle of the card
	if there's no children drivers attached.

	This likely is papering over bogosities in the power system.  The
	power sequence needs to be re-written, so I'll not worry about
	the papering over until the re-write.
