Ah ah! Mine is marked 109457-0001.
Additionally, in case there's a difference here, my PCB has 3 jumpers,
JP-1, JP-2, and JP-3. On mine, JP-1 is closed with a solder blob, the
other two are open.

Thanks for the sticker number. It's possible they are different
internally, and from the comment in one of the mailing list threads
about having to mod one of the programs for a specific model (absolute
mode vs relative mode) it does seem likely that different units come
up in different default modes.
