Intel GPU powersaving

We tried some new Intel powersaving code in the F12 cycle, but it caused 
a range of problems including screen flickering and crashes. I've 
reworked this a little and it seems to work on a machine that had 
problems in the past, so I'd like to try it again. If anyone with an 
Intel GPU (except GMA500, 810, 815 and 830) would like to give the F13 
kernels at a 
go and let me know if they result in graphical glitches or hangs that 
you don't otherwise have with F13, that would be a great help.
