the latest versions of the Duemilanove don't have the solder pads with the trace between them.
Huh. I dislike it when open source hardware published designs get out-of-sync with the versions that are actually shipping (or even non-open-source designs with published schematics.) On the other hand, it's pretty tough to keep in sync (you don't want to publish a new design for every minor manufacturing change), and the Freeduino designs seem to have suffered the same fate, so I guess I'll survive...
