--- Comment #3 from Kenneth Graunke <kenneth at whitecape.org> ---
I suspect that upgrading to Mesa 10.1 (due to be released in a few days) should
help quite a bit, though I haven't measured it.

In particular, Matt's vectorizer work reduces sequences of 4 extended math
operations down to 1.  On 965GM, extended math is done on a single mathbox
shared across all EUs (IIRC), so reducing math usage should have a significant
impact on performance.
