This always seemed a bit weird to me.  Is there any reason to choose
this form of integration.

Wouldn't it have been better to make gnome-screensaver listen for the
HAL power management events directly, and lock the screen/throttle the
screensaver where appropriate?

Similarly, why does gnome-screensaver need to ask gnome-power-manager to
power down the screen?  Isn't this a simple X call that it could do itself?

I guess the main question is: why would an app use the
gnome-power-manager interfaces to respond to power management events
rather than HAL's notifications?
