Sounds great.

I haven't set this option explicitly. This is all I have in my xorg.conf:

Section "Device"
        Option      "DPMS"
        Identifier  "Card0"
        Driver      "radeon"
        VendorName  "ATI"
        BoardName   "ATI Radeon"
        BusID       "PCI:1:0:0"
        Option      "AGPMode"   "4"
EndSection

Is there an option I can enable to speed up scrolling?

Cheers,
Michael
