direct rendering still seems to be intact,
suspend not sure(test in a moment).

Sounds like a dupe of the issue Frans reported. We report errors like
this now rather than silently ignoring them. This one must be harmless
or your machine wouldn't ever have worked. :)

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).
