Atombios includes command tables that are written in an interpreted
language. These are used to initialize the asic since the
initialization is card specific.  The driver contains an interpreter
that can execute the scripts natively on any platform.  It's been used
successfully on powerpc for example.

We released working sample code for using the 3D engine just before
new years (r600_demo, r6xx-r7xx-support branches of drm and radeonhd).
 A register reference guide to accompany the code will be available
soon.
