Thanks for the encouragement!

I can see now (by switching to a text console, catting the device files,
and wiggling the mice) that touchpad events come from
/dev/input/by-path/platform-i8042-serio-1-mouse, while trackpoint events
come from /dev/input/by-path/platform-i8042-serio-2-mouse.

Previously I tried catting those files from an xterm, which didn't work
too well (trackpoint events were visible, touchpad events weren't).

Doesn't opening /dev/input/mouseX automatically remove those events from
/dev/input/mice?  I'd like to keep /dev/input/mice for hotpluggable USB mic=
e.

Can I use the 'synaptics' driver with /dev/input/mouseX instead of
/dev/psaux?  (Reading 'man synaptics' seems to indicate that I can use
it with /dev/input/eventX.)

That would be Option "ButtonMapping" "9 10", right?

Is there a way to do the equivalent with the 'synaptics' driver instead
of 'mouse'?

Thanks,
