Isn't the write-protect sensor status available for polling?  If you
constantly (once per clock tick) check the write-protect detector, you
could see the "shadow" of the diskette sleeve (write protected or not)
as the disk is inserted or removed.  I.e., if the detector toggles in
any way, a diskette has been either inserted or removed.
