Hi Tom Stellard!
Now I updated kernel to 3.13, drm from git, radeon x driver from git and mesa from git with above patch. And patch really fixed problem with glamor rendering :-)
Here is output from glxgears
$ glxgears Default raster_config = 0x124a rb mask = 10 Final raster_config = 0x124f Default raster_config = 0x124a rb mask = 10 Final raster_config = 0x124f Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. 270 frames in 5.0 seconds = 53.990 FPS ^C
Tested also with 3.14-rc1 kernel and still working. But with old kernels (3.11) there is same problem and not working.
Older kernels don't provide an interface to query the enabled backends. It should work with 3.12.x and newer.
