Whenever the X server transitions from not drawing to drawing, the refresh rate should be increased to its normal 50hz at the next vertical retrace. Whenever the X server goes idle, the refresh rate should be dropped to a frame rate of (tbd) at the next vertical retrace.

Recent Gnome versions have dbus messages defined to allow applications (such as DVD players) to temporarily disable the screen saver/DPMS functions of the system (e.g. the Totem video player). The XO-1 power manager and activities should follow these conventions.

At this time, it does not appear that the keyboard and touchpad consume enough power (a few milliwatts) to be a significant battery drain in Ebook mode. This may need to be revisited when we transition to a new lower power wireless module. In BTest-2 and BTest-1, it was inadvertently on the wrong power rail that is not powered during suspend: this is fixed in B3.
