Since this bug is pretty much the same as previous one I had identified in
comment 29 (pointing to bug 38173) and since the proposed patch is also pretty
similar to 1 of the 2 patches needed to fix that identified bug, is it possible
there is something missing that would look like the second patch that was
needed?

patch 1 from bug 38173 (similar to the one proposed with your attachment
76544 [details] [review]):
http://cgit.freedesktop.org/mesa/mesa/commit/?id=5e1495b2d9311fa2b320766a1d299053904bd9c3
patch 2 from bug 38173 (possibly similar to what is missing to complete your
proposed patch):
http://cgit.freedesktop.org/mesa/mesa/commit/?id=acca690c259824636ef1ff684a10bd1caca4751f

In other words, are we sure we are offsetting the non_disp variable correctly
for Cayman? Because according to the second patch, the offset was different.
