The journal needs to be replayed only if you shut down your filesystem
inproperly. Otherwise there is nothing to replay.
The check after 40 mounts or so is in case some inconsistancy has crept
into the filesystem ( eg cosmic rays) which should be found and fixed
before your disk gets totally messed up. This has nothing to do with ext2
or 3
