Comment 1 for bug 450567

U??, thank you for your report. The functionality you are looking for should be available in the gsynaptics package in Karmic, at least for scrolling configuration. What you are asking for has already been requested in bug 339686. The latest version of gnome-mouse-properties in Lucid (System->Preferences->Mouse) has options under the Touchpad tab to configure horizontal and vertical scrolling.

I will update this bug's description to request that we document these touchpad options in the Lucid system docs, as well as suggest gsynaptics for more advanced configuration. The wiki page you linked to already has this information available.
