This is a fully working multitouch kext for the ALPS trackpad on most laptops. A modified version of the VoodooPS2 by RehabMan
1) Upto Five finger multitouch support
2) Two finger scrolling
3) Full intergration with Trackpad settings in the settings pane
P.S This is the package extracted from the truly awesome Vietnam tool
I uploaded the same package to osx86 so no i didn't rip this off.
