We use the following solution here:
1. Creat a user "shutdown" or "reboot".
2. Give him a password.
3. Change /etc/passwd so that a) his user id is equal to root, 
		b) his home directory is some safe place
		c) his default shell is /sbin/sysdown
4. sysdown has to be a script that calls shutdown, e.g.
  /sbin/shutdown -h now
5. create a file .xsession.linux in his home directory which calls sysdown.

Attention! In this solution, everybody who knows the shutdown-passwd
can shutdown the machine even from a remote system.

Hope this meets your needs.
