keyboard hack: how to add a trackpoint to a keyboard that doesnt have one

[elninio]

Is there a way to add a trackpoint onto a keyboard that doesnt have one? I'm asking because I really like the dell E series computers, but they don't have trackpoint. Are there any keyboards that I can buy for those laptops and swap them?
