There is currently no open source implementation of a Chrome9 3D driver
and there will likely not be any until first the Chrome9 DRM is sorted
out. Then a 3D driver using either DRI or Gallium 3D can be written, but
this depend on VIA providing some pixel shaders documentation first.
There is no ETA for such a documentation, but VIA is working on it.
