Hi,
I've been running nouveau driver for about 8 month now and did not find
any serious problem except selecting OpenGL instead of Xrender as the
rendering backend was causing the kde 4 window manager to crash at startup.
I saw that mesa 7.5 will have nouveau gallium for the 3D and that
decided to have a try. I apparently succeeded:
glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Gallium 0.2 on NV49
glxinfo | grep OpenGL
OpenGL vendor string: Tungsten Graphics, Inc. and nouveau
OpenGL renderer string: Gallium 0.2 on NV49
OpenGL version string: 1.5 Mesa 7.5-devel
OpenGL extensions:
However, I have a permanent, always reproducible crash running xbmc
Program received signal SIGSEGV, Segmentation fault.

Apart that most of the rest seems to be smooth enough.
BTW, I cannot manage git to work via
git clone git://anongit.freedesktop.org/mesa/mesa. This command computes
the remote object and then hangs forever. I have to use snaphot prvoded
via the web interface. pretty annoing.
whereas I also use git for drm and nouveau
