Mesa-solo is not X it is the OpenGL layer. mesa-solo runs standalone
without needing X. Using mesa-solo will give you access the full
acceleration capabilities of many chip families - i810, i830, i915,
radeon, r128, mga, sis, ffb, tdfx.  Nvidia is not supported because
the hardware documentation is secret. There is also a mode for
building an embedded version of mesa-solo which removes about 50% of
the OpenGL functions and makes it smaller if that is really a problem.

Check out the Cairo benchmarks. The OpenGL drivers can beat the
performance of 2D drivers 100:1 and some cases 400:1. OpenGL uses the
GPU to do the drawing instead of the main CPU.

Writing fully accelerated drivers is very complicated and it takes
years of work.
