Touchpad support missing for unl0kr

This is a feature request, but I don't really expect this to be some kind of priority. I was doing a new pmOS installation yesterday on a laptop, and had some issues with FDE for unl0kr-unrelated reasons. However, to press buttons in the UI, I needed to connect a mouse, because the touchpad wasn't working. Having touchpad support seems worth it if we want x86_64 to be a first-class citizen, even if it's a bit far into the future
