Just to help confirm/refute the BIOS/motherboard hypothesis I tried the device on my laptop also running 13.04. Exactly same faults (unusable precision using touch and buttons not working, the pen works fine). If you like I could boot 12.04 to re-confirm it's a regression and try 12.10 to help narrow it down?

I'm sure that this all worked perfectly under 12.04 without any tweaks. I'm not sure which package this is in as the code is spread between kernel modules and an X11 driver. Using Wacom Bamboo Pen and Touch, the buttons don't work and the touch motion is so excessive that it goes from edge-to-edge over about a third of the touch area. Note that touch motion is independent of settings for the pen, it is always relative in recent releases. Pointer movement is unpredictable with small movements producing both large 10+pixel step changes and small 5-pixel step changes for no apparent reason. Buttons work on the log-in page only.
