I'm not sure if Gallium3d is "replacing" Mesa..

"Gallium3D is the codename for the new Mesa device driver architecture which
is currently under development."

http://www.tungstengraphics.com/wiki/index.php/Gallium3D

"Gallium3D is Tungsten Graphics' new architecture for building 3D graphics
drivers. Initially supporting Mesa and Linux graphics drivers, Gallium3D is
designed to allow portability to all major operating systems and graphics
interfaces. "

So if I understood everything correctly you still use Mesa (as a OpenGL
library) but behind the scenes Mesa is using Gallium3d drivers..
