You might be able to create a kernel thread that polls the CDROM frequently.
(or polls it when it is not being actively read from)
If you think about the "Automatic Insert Notification" that Windows does, it
is basically just polling the media status on the drive at an interval.

If you get a "media not inserted" status, power off. :)
