If they're at the console, yes. Just use Ctrl-Alt-Delete. If you want to
give normal users the ability to remotely shutdown the system, you might
look into the 'sudo' package. It allows you to specify certain commands
that users are allowed to do as root.

The users run the asylum? :)
If that happens, just shutdown the machine and reboot into single user mode.
I don't think that asks for a password, but I could be wrong. If that
doesn't help, pull the drive and put it in another machine and mount the
root filesystem. Yank out the root password, move the drive back to the
normal machine, boot and put a new password on the root account.

Sure, compile your system with APM support in the kernel configuration and
install the apmd package (it's part of Mandrake). It works pretty well.
