given you referred to #9710, i'm assuming you think kevin is seeing
DPMS. did we reenable DPMS on XO-1? i hadn't realized that. i've
recommended keeping it off for some time, because it fights with powerd,
but maybe you've fixed that.

equivalent functionality would be trivial, with a new checkbox to
reconfigure powerd to allow dimming/blanking the screen but prevent sleeping.
this would work on both platforms.
