imagine the cirrus or stdvga driver be able to do that ever ;)

cirrus has pretty good 2d acceleration. 3D is a mega-project though.
Cirrus has no blending/compositing hardware support.
Paravirtualized graphics can easily support full XRender-style
2D acceleration.

What do that entail? 3/4 operand raster ops?

With alpha compositing.
