I know the bandwith handicap, and I know it's not possible to improve that, but 
having free CPU time while Glamo is drawing should allow to calculate things 
(as next frames) instead of waiting glamo to finish. Shouldn't it?

Correct me if I'm wrong, I have almost no idea about graphics drivers...

Should FIFO patch have some impact on "normal" (Xorg) use?
