This means that everything looks backward to the FreeBSD FS. And, the reason that byte order switching isn't done automatically is because of performance issues since every read/write would need to be checked for byte swapping. Anyway, Thor posted about Pace Willison's FS code which did this, so if you can find it it might be a good place to start.
