It behaved the same as when the wacom driver was loaded. Im going to
try and get hold of a W2k machine and use the snoop program to find
out how this device is getting initialised.
Looking at the driver I can't see any logic that initialises the
tablet. Can someone tell me where such code should go or is that done
in userland?
