I've actually just been informed that two baud rates are appropriate for Wacom devices, 19200 for pen only devices and 38400 for touch only or pen and touch devices.

If it's preferable to use the evdev driver on these devices, it might be worth filing a bug against the xserver-xorg-input-wacom, don't you think? I could do it but it would be better if someone with the actual device did it... Regards, Stephen
