Personally I think it would be a great idea, as doing this through
OpenGL is even faster than doing it through DGA.  A secondary benefit is
that it does not require root if the user is using the DRI.  We still
need some sort of dumb frame buffer access around for two reasons:

1) not everyone has a card with sufficient 3D capability or any 3D
capability at all
2) using 3D can use up a lot of power depending on the video card, and
the user might prefer to conserve that power with slower performance.

there are probably others too.  but rendering a framebuffer and 2D
primitives via opengl sounds like a good plan here.
