Wacom tablets should be backwards-compatible with the standard mice.  I
have a serial-port Wacom tablet that I could just plug in and use with X
(just configure X so it points to the device as a mouse pointer with an
"appropriate mouse type" specified as the pointer type.) - I just
unplugged my existing serial mouse, plugged in the wacom tablet, and
there I went without any extra drivers or configuring or nothin'.

Wacom also supports tilt and pressure sensitivity.  I got that to work
within an Wacom-aware proof-of-concept paint application written by one
of the Gimp developers, if I recall correctly.  I think there was also
some sort of Wacom driver involved, I don't remember - It's been really
long.  I can dig around if you need that info.

In any case, if it's Wacom-compatible then you should be able to get it
working like a standard mouse pretty easy provided there's a compatible
USB mouse device you can specify.

Looks like it's just a raw HID device driver to me from the messages.  I
would've hoped it would possibly create two devices if the system really
understood what it was, one device for mouse-compatible input and
another for extra data like pressure sensitivity.  Perhaps the USB HID
protocol allows both mouse-compatible events and extra data events to
occur in a single USB HID stream.

Eh.  Whatever.  Try it and find out.
