		* Locking:
		* The caller must not hold the IDE locks
		* The drive present/vanishing is not yet properly locked
		* Take care with the callbacks. These have been split to avoid
		* deadlocking the IDE layer. The shutdown callback is called
		* before we take the lock and free resources. It is up to the
		* caller to be sure there is no pending I/O here, and that
		* the interface will not be reopened (present/vanishing locking
		* isn't yet done BTW). After we commit to the final kill we
		* call the cleanup callback with the ide locks held.
		* The caller must not hold the IDE locks.

		* Unregister restores the hwif structures to the default state.
		* This is raving bonkers.
