Keyboard not working on Acer C720 chromebook or other Intel Chromebooks

On Intel Chromebooks, a virtual PS/2 controller is used (the keyboard is actually connected to the EC via GPIO). i8042ChangeMode causes the keyboard to stop working on these chromebooks. The best way to solve this is to check if the System Manufacturer is "GOOGLE" and then just "return TRUE;" from i8042ChangeMode without actually changing the mode.
