ah yes.  the bad date confuses powerd.  time in unix is normally
counted in seconds since the start of 1970, so your date causes time
to be reported as a negative number.  powerd discards events that may
have arrived before some reasonable time in the past -- this is
usually the time of last suspend -- but at boot the value compared
against is 0.  so all events prior to 1970 appear too old, and they
all get discarded.  (and so the DCON isn't unfrozen.)

the fix for this happens to be the very last commit made to powerd,
and was released in powerd-110.
