My fix for the Firefox 3 slow scrolling glitch on Ubuntu 8.04 Hardy was to re-add this section to my /etc/X11/xorg.conf file after running in safe mode:

Section "Module"
        Load "dbe"
        Load "extmod"
        Load "fbdevhw"
        Load "glx"
        Load "record"
        Load "freetype"
        Load "type1"
        Load "dri"
EndSection

The module section may be absent if the xorg.conf file is regenerated during safe mode or some other event. Modules like DRI should be automatically loaded, but I needed to force them in to get the necessary acceleration.

The slow scrolling happens for me on Dell Latitude laptop computers with ATI Radeon video chipsets using the default xorg.conf configuration.
