Thanks for doing this work.  This is exactly what I had in mind when I 
implemented powerd(8) the way I did ... put all of the heavy lifting 
into scripts that can be configured to do the right thing through the 
use of other tools.

Hm.  Perhaps things like AC Adapter drivers should enqueue their 
initial state when the driver attaches, and sysmon_power should allow 
certain types of events to be enqueued regardless of something 
listening on the sysmon_power communication device.  That would allow 
powerd(8) to notice the initial state of an AC Adapter as soon as it 
starts up.
