There is no acceleration eve no shadow fb in current avivo driver
which makes it slower than vesa, but avivo drivers have been
released to test out its output functionality and its capacity to
properly set video mode so far except bugs i did introduce i
have been able to fix and understand a bit better r500 registers.

Next i might, or anyother one who beats me to it, add avivo
into radeon driver than we should be able to have XAA acceleration
without too much trouble, maybe even 3d...

best,
