Sorry for the long silence.  If you get a chance, you could test v3.1-rc3
or later from mainline?  I am hoping that

	    drm/i915: Leave LVDS registers unlocked

	    There's no reason to relock them; it just makes operations more
	    complex. This fixes DPMS where the panel registers were locked making
	    the disable not work.

or a related change might fix this.

Thanks for a clear report,
Jonathan
