I'm glad I found this thread. I'm having the same problem, with a wrinkle: I'm getting "OpenGL renderer string: Software Rasterizer" from glxinfo no matter what I do, even though my Xorg.0.log seems to indicate that DRI is loading fine--at least I don't see any obvious errors.

Changing from EXA to XAA helped a lot, but I still can run my CPU up to 100% in 40 seconds running just glxgears, the LXDE desktop, and one terminal window.

I'm on a Radeon Mobility M6 LY and a custom-built kernel from Ubuntu source. Hardware is a Sharp PC MM 20 with Transmeta Efficeon processor.

I've attached my Xorg.0.log with details, if anyone would care to have a look. My xorg.conf is in the following post.
