I agree with your suspicion. My Minolta, in raw pixels gets about 8mb from a 35mm frame. With the 4000dpi scanners, a raw pixel count of about 20mb is realized.
It does seem there is more than 6 megapixels of information in a 35mm film frame. It's the "standards" issue again... and what size the final output will be. For most people 6 mega-pixels may be good enough, but "good enough" and "as good" may be two different things, depending on the user's intentions.
