Comment 200 for bug 760131

Herton - this patch would have come via stable had this kernel been in the support window, so I think its OK to leave it alone. It does not appear to be causing any regressions, and I've read reports that is has made a difference on some platforms. There are likely multiple reasons for increased power consumption, among which are mis-configured MSR on Intel, increased usage of compiz and 3D graphics, pulse audio, etc.
