Improving Vladimirs alpha test fix a bit as it turns out r300Enable didnt correctly disable alpha test. Vertex programs with high vertex count now run a lot faster as software fallback is no longer on. Also disabling 'temp to result'-instructions as they probably violate the spec and dont seem to be something thats needed.
