Comment(by lindi):
I have om-gta02-2.6.32 a9254be10ac2294ea20165a87c09ea6a and tried to
measure this with
{{{
# while true; do rtcwake -s 60 -m no ; echo mem >/sys/power/state ; om
battery consumption; sleep 10; done

but after a while I was unable to resume even with power button.
What is the recommended way to control wifi power? rfkill support is not
enabled in om-gta02-2.6.32 a9254be10ac2294ea20165a87c09ea6a
