Phoronix: AMD Radeon R600g Gallium3D: Mesa 8.0.4 vs. 8.1 Git
With Mesa 8.1 set to be released next month, here are some benchmarks comparing the Git performance of Mesa 8.0.4 to Mesa 8.1-devel for several generations of Radeon graphics cards. In this article the R600g Gallium3D driver is being put under the microscope while other articles in the coming days will look at the Intel i965 DRI driver, ATI R300g Gallium3D for the older Radeon GPUs, and the Nouveau Gallium3D driver.

I haven't been able to find any pts bisect docs.. and it doesn't appear as a module for me...
