powerd broken in os9

[Yioryos Asprobounitis]

Powerd does not work in os9. Looks like a regression. 
Apparently things have been moved around in /sys in the new build and powerd does not find the files in the expected places

/var/log/powrd.trace says:
/usr/sbin/powerd: line 911: d: unbound variable
