Comment(by pgf):

 this may be related to improvements made to the video subsystem.  i think
 jnettlet reported far less cpu used in screen activity -- he was talking
 about record, i guess, but perhaps the improvements affect other things as
 well?  i think we need a better idea of the specific kinds of places where
 we sleep now where we didn't sleep before to understand the issue.

 as for the startup ring:  powerd won't sleep if the dcon is frozen.  on
 normal boots, the dcon isn't thawed until sugar is running or gnome is
 being started from /usr/bin/olpc-session (there's also a 30 second
 failsafe timeout).  once the dcon has been thawed, the normal 15 second
 idle timeout must elapse before we'll sleep.  the timing of the first boot
 is different, than normal boots, so i guess that should be investigated.

 as always, a powerd trace ("powerd-config =trace-on", or "powerd-config
 =trace-debug") will help.
