Hello, What is the status of this regression? Can you find a better solution? I tried the suggested patch on my Xpress 200m. It does help to increase FPS in glxgears, but lockups the system periodically in 3d games. Please help. It seriously affects the 3D performance of R300-based ATI cards in Ubuntu 9.04 with Mesa 7.4. Thank you in advance.
