 Replying to [comment:3 dwmw2]:

 > If we want a rule that the system may not be woken within 5ms of going
 down, I would have thought the best way to implement that is in the EC.
 That's the only safe way to do it anyway.

 The EC has no way to control RTC wakeups - that magic all happens inside
 the southbridge.  the EC can control the power button, but Richard tells
 me that isn't a trivial matter.

 > Regarding the EC-timer... does the Geode not keep one of its own timers
 powered in the suspend domain? Timers which are slow to set up are usually
 a PITA. Although I suppose we could make the wakeup time just an extra
 argument to the suspend command...

 For the umpteenth time, the MFGPT timers can't wake from suspend.  The
 only wakeup timer that comes in the Geode circuitry is the RTC.
