[technomancy]

FWIW I've got the 13-inch Series 9 on Debian, and everything just works, including disabling the touchpad with a keystroke.

What I'd really like is to be able to disable touchpad clicks without disabling scrolling, but I understand if I'm on my own for that one.

I can disable touchpad clicks but not scrolling using synclient on my Thinkpad. In fact, I configured the whole thing to act as a scroll surface and nothing else.
