In our case, it isn't necessarily on the i810. We don't really care what accellerator 
is used as long as it works well for textures and stenciling. Depth buffering is a 
bonus, but not necessary for the majority of things that we do. Dest alpha, on the 
other hand IS.
Right now we're evaluating using the MGA- it is slower than NVidia's solutions, 
however we can modify the source. 

We don't even care if the graphics are displayed on the computer's screen. What counts 
for us is live, real-time, reliable video overlay.

We have a hard-realtime constraint in our rendering times- We must render (input and 
output) 30 FPS or the fans at home (not to mention the broadcasters themselves) 
notice/get annoyed. Can you imagine what the fans would think if they had to deal with 
frame-drop on TV? (!?!)
