Drill!!! Drill!!! Drill!!!. Even if you have the saw dust in there you're going to get good bondage from the CA and the wood. Drill yer holes, test fit the hinges, and dribble on the thinest CA you can find. Hell the saw dust in there kinda acts as a filler if you ask me. Leavin' less of a chance for the hinge to soak up all the glue and not get a good joint over the entire hinge and contacting areas.
