Here's a link to a new trackpad driver based on the code Apple just released with their new Darwin kernel. This supports the two-finger scrolling found on the new models.

This is a driver only annd doesn't include its own control panel for any special settings beyond the standard ones. That's coming though. I find that scrolling with two fingers (anywhere on the pad) is a lot more intuitive and much easier than using only one of the edges.

This also offers a very nice RMB function. Click the button while two fingers are on the pad and it's a RMB-Click instead of LMB. Very nice. much better than using a corner tap with Sidetrack.

Sidetrack also lacked support for filtering out eroneous (double) pad touches. Try this. Put one finger down on the pad and then touch somewhere else on the pad with another finger. The mouse pointer moves. The regular OS driver doesn't do this, and this new driver traps this for scroll use.

It's also free. Looking forward to seeing some config options to for things like setting a limit on the distance between the two touch-points.

There are actually a few versions of the driver, one of them allowing a circular motion to do the scrolling (like on the iPod). I have yet to try this one.
