This is nothing to do with the patches. You are running softpipe not the
the r600 driver.

libGL error: failed to load driver: r600
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on softpipe

You can try running this to get more information on why the driver is
not loading: 
$ LIBGL_DEBUG=verbose glxinfo | grep direct
