Probably not.

If you want to disable rebooting on the ctrl-alt-del sequence, "man
inittab" should help. There's also an entry in the /proc filesystem,
called /proc/sys/kernel/ctrl-alt-del, which controls wether
ctrl-alt-del is handled by the kernel or by init:

/usr/src/linux/Documentation/filesystems/proc.txt

(or wherever you keep your Linux sources).

X11 is yet another beast, of course. On the KDE I use, it appears that
ctrl-alt-del is handled by the session manager.
