Ah! This one's much easier to answer. You can tell udev to make an alias for a
eventX device when you plug it in to a more generic name that will not change
after unplugging/replugin or a hibernation cycle [1]. If you have more than
one tablet this will be more tricky though (I hope that's not an issue).
My rule is as follows (/etc/udev/rules/65-wacom.rules):
----
# udev rule for wacom tablets.
KERNEL=="event[0-9]*", SYSFS{idVendor}=="056a", SYMLINK+="input/wacom"
----
I don't think adding this rule require a reboot, but you need to update your
X-configuration file to use the generic device name.
Hope this solve your problem.
Cheers
Magnus
