I was having the same problem, and the issue isn't so much the hardware as the driver. I read a suggestion elsewhere to uninstall the Cypress trackpad driver and use the basic Windows (PS/2 Mouse) driver. Doing so removes the multi-touch gestures, but I had already disabled them in an attempt to improve the scrolling, so no big loss. With the basic driver, the scrolling lag and jumpiness is gone.
Russell is correct. I ahd exactly the same issue. I updated driver from the dell website which seemed to cause the conflict. I logged on with a Dell technician and he reinstalled the cypress driver which did the trick.
