Comment(by pgf):

 without having rerun the tests as richard suggests, i suspect the problem
 is here:

 when going to sleep, the kernel inhibits "superfluous" wakeup events:

 {{{
         /* We don't want to wake up on superfluous events */
         olpc_ec_mask_unset(EC_SCI_SRC_BATSOC | EC_SCI_SRC_ACPWR);
 }}}

 on wakeup, we used to reverse this, by enabling all wakeup events.  but
 this was disabled, here:

 {{{

 Author: Deepak Saxena <dsaxena at laptop.org>

     Don't enable all wakeup events on resume.

     Since userpsace can now set/unset individual bits in the SCI mask,
     we don't want to reset it at wakeup.

 }}}

 clearly there's a disconnect here.  the current situation feels quite
 asymmetric -- it feels to me as if either the kernel or ohm should clear
 and set bits in the wakeup mask, but whoever does it, they should do both
 the enable and disable.
