I've seen that the destination lines of my test go to the AGP addresses,
0xb0000000.

I've also tried x11perf -shmput500, which may be similar to what flashplayer
uses. I get a maximum of 53/s; What do you get, in K8M800/K8N800?

If flash takes 50% of the cpu, may be at the limit for 25fps with the 50% left..

I've tested a slightly newer notebook, with an Intel controller, and 'x11perf
-shmput500' gives 1150/s, which is about 20 times more... Shouldn't the
unichrome chip do more than 53/s?
