FWIW, this is what I did when I setup a lab full of insecure PC's.  I
simply created a custom boot loader that ignored user input.

This was the best way I could think of to make the boxes secure.  (That
and forcing the box to boot from hard-disk first.)

Since I knew the password, I could change the boot order, then stick in
a floppy to do recovery.  Yes, it was a pain, but security doesn't come
w/out costs.
