Through some script trickery, I was able to get g-s-d running in debug mode. It appears from the debug output that in 13.04, g-s-d's power plugin is *not* responsible for powering off the monitor when lightdm/unity-greeter is up. The question is: Who is?
(Power is out here, probably for a week, so I won't be able to do any more digging for the moment.)
