It makes all special keys working, adds possibility to control fan like Windows does, controls Touchpad Disabled LED, toggles touchpad state via keyboard controller and corrects touchpad behavior on resume from suspend. It is new, modified version of patch. Now it does not depend on psmouse and does not need patching of input subsystem. Signed-off-by: Maxim Mikityanskiy This is part 1 for special button handling.
