Thought I would help you out since I just finished spending an awfully long time getting my two finger click to work properly. I'm running an original white 13.3" MB, triple booted with Sn0Le0, Win7 and Karmic. (I decided against boot camp and parallels... well... because I can 😀 )Anyway, I started with the bootcamp software drivers that came on the 10.4 Le0 install disk and upgraded it until 3.1. Then once that was finished, I went into the bootcamp settings.
1) Start
2)type "bootcamp" into the search field
3)Click on "Bootcamp" which should be under the 'Controle Pannel' heading
4) Allow it to run on your computer/make changes to the HDD etc. (never could figure out why Windows had to be so complicated as to have to build something like that into it's OS in order to keep stupid people from f**ing up their computers...)
5) When you get to the Bootcamp control pannel, you should see a tab that is entitled Trackpad. Choose it
6) Select your options and hit Apply
Should work. I don't know if it has anything to do with having the CD in the drive, but it probably doesn't hurt. If you don't have the CD, it can be had a number of "unofficial" ways. Look it up, and good luck!
