I expect you will need to update the drm as well. The X server and Mesa driver use different APIs into the drm; right now the API used by the X server is implemented in the Jaunty kernel (that's what EXA and Xv use) but the API used by Mesa is not.
The r600_demo program uses the X server's API, not the Mesa API.
