Either something is seriously wrong with my settings somehow or x11-drm is 
really crappy. A have no idea.. Fact is yesterday I was forces to boot back 
in to my previous kernel since the one I created for x11-drm (i.e. with dri 
disabled in the kernel configuration) failed me. The previous kernel had dri 
compiled as modules and I have never had direct rendering working with it... 
until now..

I am very surprised by this but it turns out direct rendering is working now 
with the kernel modules. And the performance is quite a bit better than 
before:

~ $ glxinfo | grep dir
direct rendering: Yes

~ $ glxgears
6057 frames in 5.0 seconds = 1211.400 FPS
7273 frames in 5.0 seconds = 1454.600 FPS
7268 frames in 5.0 seconds = 1453.600 FPS
7275 frames in 5.0 seconds = 1455.000 FPS
7274 frames in 5.0 seconds = 1454.800 FPS
7275 frames in 5.0 seconds = 1455.000 FPS
7268 frames in 5.0 seconds = 1453.600 FPS
7275 frames in 5.0 seconds = 1455.000 FPS
7272 frames in 5.0 seconds = 1454.400 FPS
7201 frames in 5.0 seconds = 1440.200 FPS
7259 frames in 5.0 seconds = 1451.800 FPS
7270 frames in 5.0 seconds = 1454.000 FPS
7272 frames in 5.0 seconds = 1454.400 FPS

I am clueless as to why this is working now when it wasn't before...
