Which, by the way, produces a much snappier experience than the default setup which only works with agp1x.
Not sure which of those are the key settings that enable things to work with agp 4x, i don't really have the time to play around and try taking them out one at a time...
note also that i'm running on plain metacity, rather than compiz... but should work just as well...
Update:
I was able to get things to work with agp at 4x, with the following config:
###########
Section "Device"
Identifier "Configured Video Device"
Driver "ati"
Option "AccelMethod" "XAA"
Option "AGPMode" "4"
Option "AGPFastWrite" "yes"
Option "EnablePageFlip" "on"
Option "RenderAccel" "on"
Option "DynamicClocks" "on"
Option "BIOSHotkeys" "on"
EndSection
Section "DRI"
Mode 0666
EndSection
Section "Extensions"
Option "Composite" "Enable"
EndSection
