More sucky answers from the sucky answer brigade: if I close my notebook
lid, the screen remains powered on.  But if I open the lid, the screen
powers off until I swap virtual consoles between X and normal consoles.
So when I want the screen to turn off, I open and close my notebook twice.
:-)  There seems to be a message here that syscons and other bits need to
learn more about dpms, and that acpi needs to provide the necessary events
(and time) to the device tree to allow proper power management (and may
not currently do that).  This came up a number of times at the dev summit
last week.
