I have a Lenovo y700 laptop.
I installed the VoodooPS2Controller provided by RehabMan.
Detection of keyboard was fully successful.
Detection of touchpad was somewhat successful. One finger works, I can move the mouse. Two fingers does not work, so I can't even scroll websites.
The touchpad is not detected in System Preferences.
I then researched something more.
From Lenovo website, the driver for Windows says the manufacturer is "Elan, Synaptics, ALPS", so no help there.
I then found out...
Keyboard and Touchpad Compatibility
