From the point of view of a user I would like to be able to:

1) Use hardware acceleration for most projects (Cedartrail, in my case);
2) Use EGL/GLES and possibly GL;
3) Run with X;
4) Run with just a framebuffer (no X at all, so no hardware accel?);
5) Have pvr support with kernels later than 3.0.

At the moment I have to do quite a bit of hacking of MESA to do this, especially when using openGL (via osmesa) to 'help' some legacy framebuffer code that runs under SDL. It would be really nice if mesa could be made to take some notice of DISTRO_FEATURES (e.g. X11) and build a 'sensible' version.

So, my 'vote' would be to include a working version. Please :-)

More than happy to help out if there's anything I can do...
