Radeon Gardenshed DRM + Gallium3D Benchmarks

Radeon Gardenshed DRM + Gallium3D Benchmarks: It has been about a month since we last delivered ATI/AMD Radeon Linux benchmarks comparing the performance of the open-source driver against the high-performance proprietary driver. Since that point there's been various improvements to the Mesa/Gallium3D driver and there's also been the merge of the latest Radeon DRM code for the next kernel, which will likely be called the Linux 3.0 kernel, but in the DRM pull request was referred to as Gardenshed. Here are these benchmarks on several different Radeon graphics cards.
