Ah so we're inheriting the FB 2x, once with 1280x1024, other with 1366x768:

kern  :debug : [   74.880444] [drm:i9xx_get_initial_plane_config [i915]] pipe A/primary A with fb: size=1366x768@32, offset=61000, pitch 5504, size 0x408000

kern  :debug : [   74.885295] [drm:i915_gem_object_create_stolen_for_preallocated [i915]] failed to allocate stolen space

Which of course fails, but should be an interesting case to handle right. :)
