v0.9 seems to work well on my Dell E6410 now that I'm running Natty. (Just upgraded from Maverick--and had to fight with a broken GRUB due to the upgrade! There's a reason I'm 6 months out of date.)

Two-finger scrolling works, horizontal and vertical edge scrolling work, and it seems to disable the touchpad when typing. I cannot seem to affect the pointer speed with the "Sensitivity" adjustment on the "General" tab of Mouse preferences, but the "Acceleration" slider definitely has an effect. No problems with jitter.
