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
 rtcwake: wakeup from "no" using /dev/rtc0 at Sat Jul 31 16:52:54 2010

 }}}

 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
 defconfig_gta02
