--- Comment #3 from Ville Syrjala <ville.syrjala at linux.intel.com> ---
Let's not be so hasty closing this one. Real world trumps any spec, so I think
we should make i915 handle this case more gracefully.

I think what we want to do is explicitly check for the DC_36bit thing. I've
even written that exact patch once but decided not to send it out since I'd not
seen any monitor that would violate the spec in this manner.
