Once we have the permission manager from bug 707625, we need to hook up screen.mozEnabled and screen.mozBrightness to it.
Until we have a new permission manager, can we use the 'old' one to hook up those properties to the content?
We're already using it for indexedDB, offline-storage, webapps-manage, etc...
I remember it being said to steer clear of the old permissions manager.
FWIW, right now we're doing pref-based "permission management" in WebSMS and the browser API stuff I've been doing.
https://docs.google.com/spreadsheet/ccc?key=0Akyz_Bqjgf5pdENVekxYRjBTX0dCXzItMnRyUU1RQ0E#gid=0 says this Permission Name is "power".
I'm apply the process-level capability check in bug 776835.
Fixed in bug 781353
