Forgot to add: I'm using an Aiptek SlimTablet 600U (Model WCK-C121) and
have NOT installed xserver-xorg-input-aiptek but xserver-xorg-input-
wacom (the tablet also uses the "wacom" kernel module). The problem
seems to be the same though. So it might have nothing to do with the
specific input driver.

dmesg when "rmmod wacom" before unplugging:
