OK, stylus and eraser aren't being appended to the parent device Pen and neither are touch and pad to Finger. This means you are not on the Wacom X driver xf86-input-wacom. Likely the tablet is on the evdev X driver.

This is probably due to a (now longstanding) bug in Lucid where your 10-wacom.conf disappears due to an update. Or maybe isn't even put in anymore on a fresh install?

Either the 10-wacom.conf is empty or isn't at /usr/lib/X11/xorg.conf.d. So manually install a 10-wacom.conf and reboot and see what happens. Instructions are in part III. along with an example wacom.conf.
