[REQ] Laptop (slider mouse plus no numpad) controls.

Hey all, like many of you i use a laptop to play sh3 + GWX3 on the go, i'd love to do this but many controls are difficult or impossible to use, and looking around is a chore with the slider pad, but i dont want to carry around a mouse with my laptop, as it works as a gigantic netbook just fine. Can anyone point my in the direction of some sympethetic modders.

or just give me some tips?
