Motion is still a problem with gutsy on a Dell D600.

Just did a fresh install of Gutsy Gibbon on Dell D600. Tapping and scrolling work fine, Motion is smooth but painfully slow. Mouse GUI doesn't affect touchpad motion, but does affect knob motion, and the range is good. Tried adding this to Synaptics section of my otherwise unadulterated xorg.conf:
        Option "MinSpeed" "0.3"
        Option "MaxSpeed" "0.6"
        Option "AccelFactor" "0.0002"
Had no noticable effect on touchpad motion.

Changed above lines to this:
        Option "MinSpeed" "1.0"
        Option "MaxSpeed" "1.0"
        Option "AccelFactor" "0.3"
And the result was immediately noticeable, and much improved. 

Tried this:
        Option "MinSpeed" "0.8"
        Option "MaxSpeed" "0.8"
        Option "AccelFactor" "0.03"
I liked the 1.0 speeds better, but I think the AccelFactor is still too high, as I keep overshooting my target.

Couldn't find any version of 0.14.3+seriouslythistime-0ubuntu3 to test,
sorry.
