Cool.

Hmm, I don't think acceleration is that important here.  2D acceleration 
likely disappeares in graphics hardware soon.  I'd say a simple, stupid 
framebuffer for installs is perfectly fine, for accelerated graphics its 
probably more useful to skip 2D altogether and look at OpenGL 
virtualization instead.

just my 2 cent,
