Aaron Adams’s Blowhard Blog

In case you missed it elsewhere, the helpful developer at this site has created a kernel extension that enables certain older Apple notebook trackpads to behave like the new trackpads on Apple’s recently introduced PowerBooks. I’ve been using it for the past few days on a previous generation Aluminum PowerBook with no problems. I can’t compare it to Apple’s implementation because I haven’t used a new PowerBook yet, but it’s certainly an interesting way to scroll through long web pages or documents.

If your notebook is compatible (instructions are provided on the page to find out if it is), it’s worth a try. Unloading the Apple-provided kernel extension and replacing it with this different one currently requires some Terminal magic, but the page provides very good directions how to do so. The developer states that he’s working on an installer package and a preference pane for future release.
