I am fairly sure you could just create a script that had the shutdown commands in it, then setuid the file (which is owned by root). Then you should be able to run the file as a normal user except it would get elevated to root privleges when ran. I don't have a beowulf in front of me right now so i can't test it but i do remeber doing something simlar before and having it work. For help with setuid and setguid check out the man page for chmod.
