Seems harmless to me, one thing I see is
during the boot process Ill see the boot messages, then once
init/udev starts up, and loads i915 the screen will go black
for a tenth or so of a second, then goes back to normal. Now keep in mind
this might be something suse does during the boot process.
(I can try loading ubuntu/debian to see if the affects are the same
once I get a chance).
