drm/i915: Allocate fbcon from stolen memory
should work around the issue. Note that this happens everywhere you have more
than 1 display connected when booting, and the native resolutions are
different. The surplus area on the higher-res screen which is not used by the
kernel fbdev console is not properly cleared and contains garbage (noise
usually for fresh boots, old screen contents sometimes when rebooting).</pre>
