Yes, if the filesystem really is a SunOS 4.* filesystem, it will be
big-endian.  Your Linux FFS support has to be prepared for big-endian
data structures on disk, which if you're on a little-endian
architecture like i386 it may not be.

That presumably-root partition is only some 46 megabytes.  If you can
get a dd image of it to me (offlist!), I can poke at it; I've written a
bunch of tools for working with such things.
