I just discovered the following information:

The 

    VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE

error is because two fields in the superblock don't match.
The following is from running fsck's setup.c:readsb() routine under a debugger:

sblock	(the "main" superblock) contains:

fs_maxsymlinklen = 0, fs_inodefmt = 0, 

while altsblock (the "alternate" one) contains:

fs_maxsymlinklen = 60, fs_inodefmt = 2, 

Does this ring any bells?  I would think that the primary superblock
would get updated first, and then the alternates..

I don't have time right now to figure out why the superblock doesn't
get written back correctly..  more later..
