I use a little script at all my home machines that you may like, too.

The trick is: The Xserver is running as root anyway, so if you can get
the xserver to run the shutdown command, there is no need to mess with
sudo etc.

The script inserts two littles buttons in the xdm-screen: One for
shutting down, one for reboot.

Installation is simple. Put the attached tkmgr-script in /usr/local/bin

You have to edit two config files. First put the following at the end of
"/etc/X11/xdm/Xsetup_0"

# ---- snip Xsetup_0 --
# Starting the shutdownmanager:
/usr/local/bin/tkmgr &
echo $! > /var/run/tkmgr-pid
# ---- snip -----------

Then put this in "/etc/X11/xdm/Xstartup_0":

# ---- snip Xstartup_0 --
# :0 specific startup commands go here

# Kill the Shutdownmanager:
if [ -f /var/run/tkmgr-pid ]
then
  kill `cat /var/run/tkmgr-pid`
  rm -f /var/run/tkmgr-pid
fi
# ---- snip  --


That's it.

bye
