You don't have to be root.  Any member of wheel should be able to do
the shutdown.

As for the three-fingered-salute approach to killing the system, it's
been asked before.  My first thought is "shutdown -r now\n" is only a few
more keystrokes, and you don't even have to push any of those keys
simultaneously.  (^&

My second thought is that if you really want this, you might be able to
modify the keymap in some way so that pressing those three keys expands
as a macro to the shutdown command.  That might be the least intrusive
way.  Failing that, you could do something icky in the keyboard handler.
