you can have two wacom devices though it's unlikely you see two serial ones.
the symlink issue with two devices is reasonably well known and some
distributions ship the symlink for usb devices as well (plus a whole bunch
of model-specific symlinks). the symlinking dates back to pre-X server
hotplugging support, having /dev/input/wacom in your xorg.conf was more
convenient than changing device paths. It's obsolete imo now but as I said,
some distros still ship it..
