Ups, I got lost. So do we drop idea of using xf86-video-modesetting
for SI? I though we want to use xf86-video-modesetting and some
Gallium state tracker for 2D acceleration.
What's the difference between handling 2D acceleration in:
2) xf86-video-modesetting + X/Gallium?
Also one question for below:

Could you explain what is glamor? I was sure it is supposed to provide
2D acceleration using OpenGL. What do you mean by providing 3D
acceleration with glamor?
