The hangs with 3D on K8M800 are well known and probably unrelated to
AGPDMA being enabled or not. Can you reproduce the hang with AGPDMA
enabled and unichrome_dri.so desactivated (rename it or whatever) ?
To follow up on the VM800 problem, it seems it is a screen repaint
problem, not a hang problem. Andrey, can you please confirm what
affected you, hard lockup or screen repaint ?

Xavier
