NextStep also put a bunch of extra stuff in the *middle* of the
superblock and cg blocks.  IIRC OpenStep retained these fields.  That
was a real pain..

Looking at the OS X newfs and fsck manual pages (unfortunately, on my
only OS X box I can't create an FFS to check right now) it looks like
I was wrong in my earlier message; the on-disk format seems to be derived
from 4.4BSD, and the gemoetry defaults have been changed.  I suspect that
extra stuff jammed into the superblock is all that's causing trouble.
