Hi I have a Dell D620 Laptop with an ALPS trackpad Running Snow Leopard. Overall your kext is working great but its very sensitive when scrolling on safari, but it will not allow adjustment from the "voodoo" trackpad pref because it closes out when adjusting the settings. but I was able to turn it on with the "vanilla" trackpad pref by adding vendor ID 1452 to the Info.Plist. is there a way to build the sensitivity and relocate the scrolling to lets say the right side and bottom of track pad in the voodooALPStrackpad.cpp file? I was using a kext that was modified by Slashack that works in this manner but it outputs debug info so it is constantly outputting tracking parameters to log which is killing my battery life from from all the hard drive access.. the problem is there is no source to compile from to remedy the situation of debug output but there seems to be a Patch.diff but i'm not 100% sure if its correct. I can supply it to you if you wish.
And thank you for your time and many effort you have supplied the Hackintosh community over the years.
