Progress! Applied that patch to 4.0 rc3 and recompiled:

However, touching the screen does not cause the pointer to move and more
empirically:
(From /proc/bus/input/devices)
I: Bus=0018 Vendor=03eb Product=8c1f Version=0100

Doing
cat /dev/input/event14
or
cat /dev/input/mouse1
and poking the screen gets me no output.
