Thanks!  I look forwarding to *not* running a hacked-up kernel soon.

It reports as touchpad with a single button.  This makes the kernel
report it as a "clickpad".  In particular, this means that libinput
knows to make clicking in the lower-right turn into a right-click.
With out that, there was no way to right-click since it reports as
having a single button.  Benjamin could tell you more than me.
