        <pre>Macbook Pro 8,2 Late 2011 with Radeon 6750m like Ludovic Watteaux. 

In order to get the power profile working with the kernel 3.8rc4 I had to
revert the following commits:

"drm/radeon/pm: fix multi-head profile handling on BTC+ (v2)"
27810fb2d2edacf2961dbedfe9e9f8d2e5080ea5

"drm/radeon: only adjust default clocks on NI GPUs"
2e3b3b105ab3bb5b6a37198da4f193cd13781d13.

And apply the following:
