It's written against drm-intel-next-queued at

http://cgit.freedesktop.org/~danvet/drm-intel

I've thought that it should apply pretty cleanly against older kernels,
too. Apparently it conflicts a bit in intel_modeset_setup_hw_state, you
can just do the s/intel_crtc_restore_mode/__intel_set_mode/ change
manually.
