Subject: [PATCH] UBUNTU: SAUCE: input: Cypress PS/2 Trackpad fix 

Fix "Quickly clicking touchpad results in double click (with tap
to click)" by setting INPUT_PROP_BUTTONPAD property. This lets
xserver-xorg-input-synaptics know that the touchpad has a button
underneath it so it can take care of the multiple-click-source
