Considering how much is already going on, I seriously doubt that the CPU
is going into any power-saving sleep states.  Just watch DBUS with all
the power related messages coming across the bus.  That doesn't include
the fact that network manager is updating it's icon every five seconds
or so (why does it flicker now?).

I'm not saying that we shouldn't have that as a goal.  But I seriously
doubt that switching from flying Ubuntu logos to a blank screen (not
DPMS, but blank) will have a serious impact on power.

I'm not quite sure how to measure (removing all the variables like HD
access and such) but I'd have to say that I'm a huge skeptic of the
gains here.
