IMHO we only need two versions: big-endian filesystem with big-endian 16bit indexed bitmaps and little-endian filesystem with little-endian bitmaps. The rest is just the result of careless copying. Note that the minix filesystem does no byte swapping, so native byte order is the only sensible mode.
