How about copying the fixed superblock with dd(1)?
Something like this:
dd if=/dev/ad0s1d of=/tmp/sb skip=32 count=16
dd if=/tmp/sb of=/dev/ad0s1d seek=16 count=16
fsck /dev/ad0s1d
Those commands are just off the top of my head -- I
haven't
tested it, no guarantees, you're doing it at your own
risk
and you should have a backup.

Thanks, this did the trick. The only odd thing I
could say is that newfs -N didn't list 32 as a
superblock(fsck told me it was the one being used), I
first tried 92640 which was listed after 144. The 32
block worked and the others didn't.. odd.. Thanks a
million =)
