Well, I don´t know. When it uses indirect rendering, then it seems that 
the driver check doesn´t work with Intel from Mesa 7.11 indeed.

I think I need to force it to use direct rendering in that case, since 
direct rendering is available on that machine:

martin@merkaba:~> glxinfo | egrep -i "(direct|OpenGL)" 
direct rendering: Yes
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile 
OpenGL version string: 2.1 Mesa 7.11
OpenGL shading language version string: 1.20
OpenGL extensions:

I think there was an environment variable for that...
