Apparently it doesn't work. X-tiled self-refresh works flawlessly otoh. Apparently X still works correctly with linear framebuffers, so might just be an issue with the initial modeset. It's unclear whether this just borked wm setup from our side or a hw restriction, but just disabling gets things going. Note that this regression was only brought to light with commit 3f2dc5ac Author: Ville Syrjälä <ville.syrjala@linux.intel.com> Date: Fri Jan 10 14:06:47 2014 +0200 drm/i915: Fix 915GM self-refresh enable/disable before that self-refresh for i915GM didn't work at all. Kudos to Ville for spotting a little bug in the original patch I've attached to the bug.
