This patch series is an initial version that implements support for ARB_transform_feedback_overflow_query on i965. It does that by storing the initial values of generated and written primitives on glBeginQuery, and final values on glEndQuery, and then comparing those values.
I still need to write piglit tests for it, so it's not very tested, but the basic functionality seems to work fine. Any feedback is welcome.
