OK, so in summary:
Mesa 9.0 in quantal reports:
OpenGL vendor string: VMware, Inc.
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 0x301)
OpenGL version string: 2.1 Mesa 9.0
which makes Unity slow (bug 1055936).
However Mesa 9.1 reports:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Ironlake Mobile
OpenGL version string: 2.1 Mesa 9.1-devel
and everything works nicely.
