Check the X server sources, directories xc/programs/Xserver/hw/xfree86/xaa*
XAA is XFree86 Accelerated Architecture, a server internal API to make
the primitives of an accelerated video card available to the server DDX
layer. Basically, to add a new card to the SVGA server, you create a new
driver bz implementing some or all of these XAA functions.

Definitely.
