I wrote some patches to improve performance. You'll need to apply them to the git master of each project as of March 17 2010.
these instructions should work on gentoo other distributions are on your own
Instructions
"mkdir experimental"
"cd experimental"
"git clone git://anongit.freedesktop.org/mesa/drm"
"cd drm"
copy the file libdrm_radeon_cs_h.patch to this directory
"patch -p1 <libdrm_radeon_cs_h.patch"
"./autogen.sh --prefix=/usr --exec-prefix=/ --disable-intel"
"make -j3"
"sudo make install"
"cd .."
"git clone git://anongit.freedesktop.org/git/mesa/mesa"
"cd mesa"
copy the file mesa_patch_Mar_17_2010.patch to this directory
"patch -p1 <mesa_patch_Mar_17_2010.patch"
"DRI_DRIVERS="r600,swrast""
"./autogen.sh --prefix=/usr --with-dri-drivers=$DRI_DRIVERS --disable-gallium"
"make -j3"
"sudo make install"
"cd .."
"git clone git://anongit.freedesktop.org/xorg/driver/xf86-video-ati"
"cd xf86-video-ati"
copy the file radeon_Mar_17_2010.patch to this directory
"patch -p1 <radeon_Mar_17_2010.patch"
"./autogen --prefix=/usr"
"make -j3"
"make install"
let me know if you see an improvement. glxgears is not a benchmark!!!
