I think there has to be a real solvable puzzle here. If it was just broken the devs or CM team would have chimed in by now. Keeping silent implies there is something.
Another possibility is, that there's no puzzle currently, but bioware's planning to implement one soon, after they've seen people actually asking about the tome. That way, they don't have to say "there's no puzzle" and "now there is one!" after a few weeks. I assume that Bioware stays silent until there's a puzzle, and then they'll give the community a hint. In that case, Bioware doesn't even need to admit, that there's no puzzle at the moment.
