I know that my touchpad is capable of it. I can enable glitch-free two-finger scrolling by running this script:
#! /bin/sh
synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1
synclient EmulateTwoFingerMinW=10
synclient EmulateTwoFingerMinZ=48
However, in the "Mouse" preferences GUI, the "two-finger scrolling" option is greyed out. It worked fine on my old laptop.
Here is the output of sudo lshw -sanitize, if it makes a difference.

(Oh how I long to have 200 rep so I can just do this housekeeping myself.) – dgw Dec 16 '10 at 2:06
