Building Gallium3D
basic research
setup Ubuntu Lucid (10.04) x64
sudo apt-get mesa-utils
glxinfo | grep -i render

Gallium llvmpipe is what we need and a kernel driver called vmwgfx driver
vmwgfx
The vmwgfx kernel driver source can be found at: http://cgit.freedesktop.org/mesa/vmwgfx/commit/ direct download link sources: http://cgit.freedesktop.org/mesa/vmwgfx/snapshot/vmwgfx-master.tar.gz
In order to built the kernel module you'll need to have the kernel headers installed. No Configure step is needed. Just run:
make make install
The install doesn't appear to copy the kernel module into the kernel driver tree for whatever reason, so copy by hand:
cp vmwgfx.ko /lib/modules/2.6.33-020633-generic/kernel/drivers/gpu/drm/vmwgfx
(create the vmwgfx subfolder first)
Doesn't work either....

Mesa
Gallium3D is part of the mesa drivers The mesa drivers can be found at: http://cgit.freedesktop.org/mesa/mesa/commit/ and a direct download link for the source:
http://cgit.freedesktop.org/mesa/mesa/snapshot/mesa-master.tar.gz
http://www.x.org/wiki/radeonBuildHowTo
# cd xf86-video-radeonhd/ # ./autogen.sh --prefix=/usr # make # make install
This should install the RadeonHD driver for you. Please note that it might be nontrivial to completely uninstall the driver now.
Also note that you can also drop off the --prefix=/usr part so the driver will be installed to /usr/local. You should at this point find out which path your X downloads its modules from. The next will prepend module search directory under /usr/local before the one which in many computers is the default X.org module path. Not that this can cause your X not to start if main module path is changed for some reason so don't forget this setting's existence. The second path needs to be the real X.org module path.

./autogen.sh --prefix=/opt/xorg
Now without gallium-llvm (this is the only one that compiles OK)
./autogen.sh --with-driver=xlib --prefix=/opt/xorg
