I want to build an OpenGL based system without X. I know this will be possible with the open source ATI driver in the near future with KMS, ati_dri.so, and EGL/miniGLX. (With a little bit of hacking of course.)
The open source driver is WAY too slow.

I want to know if there is the possibility of using KMS, fglrx_dri.so et al., and EGL/miniGLX? Are there things in the Catalyst driver that are preventing this?

I have a system running with X now, but it doesn't really use it. (Other than the obvious screen buffer.)
