2579 - power saving (un)setting was not in effect

[Mikus Grinbergs]

Just now (with olpc-update while using 2577) installed joyride-2579 
on my XO, and booted it.  To my surprise my XO went into suspend 
when left without input - file /etc/ohm/inhibit-suspend was absent. 
  But going to the 2579 graphic control panel - it shows both 
"power" checkboxes UNmarked.  Previously, when running 2577, that 
control panel setting resulted in file /etc/ohm/inhibit-idle-suspend 
being present.
