Under discussion[1].  Not in drm-intel-next yet[2].

I suspect a different, more targetted patch[3] would do a better job
of addressing the described use case:

 1c8ecf80fdee4e "drm/i915: do not enable RC6p on Sandy Bridge", 2012-02-14

It can be found in the drm-intel-fixes tree[4].

Hope that helps,
Jonathan
