What vintage is your fsk_ffs binary?

If it's 1.6 you should get the latest 1.6.2_RC3 one and replace it, see
the entry in src/UPDATING copied below.

20030402:
        The superblock layout for FFS was changed.  If you have 1.6
        fsck binaries, they will signal a fatal superblock mismatch
        with the first alternate, because they compare too many
        fields (even ones that aren't useful).  If possible, upgrade
        your fsck_ffs binary before using a new kernel.
        None of this signals actual filesystem damage.
