EXA is bound to be slow on 965 until we land the render fixes (currently
sitting on intel-batchbuffer, but we could probably just cherry-pick
them out since they're orthogonal to the batchbuffer work).  But if
you're seeing issues on 915 or earlier, the only improvement we're
expecting to see is from TTM-backed buffers, which might help if you're
limited by migration (or might not).

If you're seeing performance issues on 915 or earlier, profile now
because there's a good chance that what you're seeing doesn't have a fix
in the pipeline.
