Sorry, I just got into the tail end of this thread, but under Linux
the behavior is:

1) Under console, Ctrl-Alt-Del on (almost?) all architectures has the
   same effect as running reboot as root.

2) Under X, the combination has no effect.  A reboot can be done by
   Ctrl-Alt-F1, Ctrl-Alt-Del.

This would imply that setuid apps could prevent the combination from
doing anything, but I don't have frequent occasion to test it and
almost never work out of X anyway.
