Agree, gsynatpics used to be installed and enabled by default back in Feisty. As of Gutsy it was cut, though luckily I wasn't forced to remove it during the upgrade. The options given by the Mouse settings are horrible and lacking, but with the SHMConfig-based tools give me all sorts of things I use regularly (like circular scrolling, sensitivity settings, etc.).
Start on the right side of your touchpad, go to the middle and do circles for srolling.

In Intrepid, one can use the command-line utility 'xinput' to set most of these options on the fly - without altering xorg.conf or enabling SHMConfig. I hope to make the GNOME touchpad configuration GUI somewhat more complete for Jaunty.
