Yes, it works, and glxinfo reports that direct rendering is enabled, but it is 
soooooooooooo sloooooooooooooow :(

I've just installed mesa/libdrm/xf86-video-intel from git. And any GL-game is 
still really slow, even Secret Maryo Chronicles :( compiz works, but effects 
is not smooth, wobbly windows effect is slow, animation effects are slow... 
GL_EXT_framebuffer_object and GL_EXT_pixel_buffer_object appeared in glxinfo, 
but qtdemo still says that there's no pixel buffer support on my system, 
framebuffer object demo works but with artefacts (see attached screen shot), 
framebuffer object demo-2 works without issues.

glxgears shows ~300fps, better that before, but it is not 900 fps as with 
non-gem kernel :(

So, I'm going back to 2.6.26 kernel...

P.S. When all this GEM-stuff will be ready for testing on my gma950?
