As far as evdev is concerned those are almost certainly just perfectly
normal buttons, i.e., they send a 'button press' event. The fact that
they also function as part of the touch-sensitive surface is probably
irrelevant. So evdev would see your touchpad as one with buttons, and
wouldn't enable tap-to-click.
If memory serves (which, in my case, is always questionable), that matches
my experience: I had to enable the feature; it wasn't on by default.
