Yes, I have found the problem here.  The "last reported state" value is 
not being initialized (well, it is, but not to a reasonable value), so
every sensor registration ends up triggering a "Changed from <no-such- 
state> to Normal" event.  Since these happen before powerd has been 
started, they get reported on the console via printf().

I'm in the process of fixing now, by properly initializing things:

  PENVSYS_TYPE_BATTERY is initialized to ENVSYS_BATTERY_CAPACITY_NORMAL
  PENVSYS_TYPE_DRIVE                     ENVSYS_DRIVE_EMPTY
  PENVSYS_TYPE_<other>                   ENVSYS_SVALID

Changes are being compiled and tested now.  Assuming there's no problem 
I will commit later this evening.
