Hi Jonas,
I had the same problem. my tablet's product id is 0094 before I know,
and Tablet not working.
So, I built linux kernel 3.6-rc1 and boot it, then the problem is resolved.
Please don't do "reboot", do power off ( "shutdown" ) and next do power on.
Now I can use stylus, eraser, and touch. tablet's product id is 00E6.
My environment is below:
PC: Thinkpad X220 tablet ( don't update the firmware )
distribution : Gentoo Linux 10.1
linux kernel:
trouble ocurred: 3.5, 3.5.1
touble resolved: 3.6-rc1
Xorg server: 1.12.3
xf86-input-wacom: 0.15.0
