It works! After sleep/wakeup, the trackpad still works!
Many thanks! I think this is a great work!
One more small question though,
the trackpad's sensitivity experence is worse that the previous one i used (VoodooPS2Controller.kext).
Tap function seems very sensitive sometime but then not so much.
Does there has some parameters that i can adjust?
I looked into the Info.plist in Trackpad, but seems not so much for adjust.
Sometimes it seems you need to tap twice to function, for example,
One tap on the yelloew button to minimize any window to the Dock, but it does not, you need to tap again, then the window minimize to the Dock.
Then one tap on the application icon in the Dock should resume the applicaiton,
but it shows a right click menu "Open this application"
tap again, the application window resume.
