I can confirm that this is an issue still in the latest Dapper with the latest ksynaptics package and synaptics driver. It appears that the problem is that ksynaptics requires a later driver than ubuntu provides and therefore cannot actually control the touchpad. I would love to have this working as I would love to have a way to turn off the touchpad on my laptop so I don't continually hit it while typing.
