What model is your notebook exactly? Is direct rendering supported by the "X" server as reported in "Xorg.0.log"? Did you ever manage to get direct rendering work for previous releases? Do you still obtain the error message:

...
 libGL error: drmMap of framebuffer failed (Invalid argument)
 libGL error: reverting to (slow) indirect rendering
 display: :0 screen: 0
 direct rendering: No
 ... ?

I have an "IBM ThinkPad T23" like Giorgio. For older models T20-T22, success is less certain. Also make sure that the video memory is sufficient for direct rendering. Try "16bpp" and a resolution like "1024x768" to start with.
