Thanks.  I thought that might be the case but couldn't find anything online
which specifically stated root is required.

This old post is what got me thinking wheel or operator should be able to
do it, but I guess there's some misunderstanding of how XFCE actually
performs suspend/shutdown/reboot:

In the past I've always used full-blown DE's like XFCE and had to set the
rights in PolicyKit, but now using cwm so I need to use commands for these
types of tasks, and just kind of assumed I should be able to do it without
root access.

I thought about poking through the acpi code but decided to leave it as a
future project :)

My solution for now is to install sudo, set the following in

%operator ALL=(root) NOPASSWD: /usr/sbin/zzz

Then set the following in .cshrc:

alias zzz       /usr/local/bin/sudo /usr/sbin/zzz
