actually...i don't think we get off that easily.  one of the labs i
used to work in had these ugly gateway 2000 486/33 machines with these
big funky keyboards (i hated 'em; not tactile enough) with not four
but eight arrow keys and other "fun" features like programmability.
you could basically have the thing record keystrokes.  i once saw one
of the admins log in, poke around a bit, crash the machine, and reboot
it.  when it came back up, the keyboard logged him in.

assuming you could hack root on one of these machines, i imagine it
would be rather easy to tell/program the keyboard what to type to set
the securelevel back to 0...
