What does this mean? All laptops that I have use touchpads that work in 
absolute mode (Synaptics or ALPS) and they work fairly well. The Synaptics X 
driver understands the difference in tablet vs. touchpad and does the right 
thing for touchpads.

You just need to make sure that X actually uses Synaptics (xf86-input-
synaptics) with your device, emitting BTN_TOOL_FINGER should help a lot.
