Finally got the need to install XP on my MBP. I have installed all the drivers from the Bootcamp CD, now I really miss 2 finger tapping, or, well, any tapping on the trackpad at all!!! How do I enable it?
There should be a Boot Camp icon in the bottom right-hand corner near the clock (it's a blackish-grey square/diamond). Clicking it should open up Boot Camp preferences, and there should be a trackpad tab
I managed to get tap-to-click working on my early 2008 MBP (non-unibody). I don't think it'll work on models earlier than that since the Rev. E MBPs were the first ones to have multi-touch trackpads. Basically, you need to manually install a set of newer trackpad drivers+newer Boot Camp control panel than what's provided on your Leopard DVD.
Huge understatement - they're not just poorly written but they're also poorly supported. I'm having to manually install newer Apple/nV/Marvell/whatever drivers from newer versions of Boot Camp (via BitTorrent) or elsewhere on the internet since they aren't even available on apple.com.
