lost data

[bobby at plexuscomp.com]

I made a very stupid mistake.  Ran an fsck from netbsd on a freebsd
partition.   Thought it was running on the net disk.  It "fixed" a bunch
of errors.  After I realized what I did freebsd would not boot.  So I ran
fsck from fbsd.  I now have a lost+found directory that is way too small,
at least 16GB unaccounted for.  Files are stored as inode # I think.
example: #0354382.  I restored a few different superblocks. nothing.
I'm running gpart on it now... I don't think its going to help.
Any ideas or tools that will help?
