I would think that painted ceiling would help you out if you choose to skip the venting. That is it's a vapor barrier to the wood.
So on skipping the venting; if it were my house, I would accept that the construction is what it is --Venting was not part of the original design-- and move along. ...Add another vapor barrier under the Cedar (or whatever).
btw, what is the big driver for insulation? is it to stay cool in the summer, or warm in the winter?

Really to try and keep cool in the summer. The house was originally built as a beach home with zero insulation. Later they came and blew a little cellulose into the exterior walls and in the ceilings where I have a regular attic. It's never been adequate though. We don't have AC and really don't need it here. It's a rare event to get into the high 80s and above. Both rooms with the beamed ceiling are southern exposure and the temp spikes like crazy in the afternoons. I've already been systematically installing fiberglass in the walls from the inside all along the exterior. The ceiling is the last piece.
