After booting several times and trying to use Ubuntu, I got again 3d acceleration, but after rebooting, no 3d acceleration again (Compiz doesn't start, glxgears as in the screenshot). This is the same behavior that I observed in Maverick, but I solved that disabling KMS. Now, with the Gallium 3d drivers, as noted by Bryce, that workaround is not an option. All I can do for now is to install Unity-2d and to use software rasterization (`export LIBGL_ALWAYS_SOFTWARE=1` and then executing the program), and activating Metacity composition, but of course, software rasterization is very slow and it's "acceptable" only if the window of the program is very small... It's strange. In Lucid radeon driver worked fine and out of the box...
