Inertial scrolling on older Macbook Pro

[w00t951]

Does anyone know if there is a <free> way to enable inertial scrolling on the older, Core 2 Duo Macbook Pros?

Found this .. works well but not free. 🙁

Also works in conjunction with BetterTouchTool which I was worried about

Someone's gotta be working on getting the features from new MBPs on to older ... anyone?
