unfortunately I did run the disklabel route and everything checks out.
I have fdisk'd, disklabel'd, and reconfigured my drives so many times I

have dreams about it. The only difference between my box at home 
and the one at work is that I ran a cvsup and portupgrade on my one
at home when I was doing the initial install. Is there a possiblity
that
the fsck binary is somehow the wrong rev.? I am trying to understand
how fsck determines the filesystem, and I thought this was done by 
checking the superblock. However, it seems that the superblock only
denotes one definition of filesystem type (e.g. FreeBSD, vinum, etc.) 
and not the other definition (e.g. ufs, ext3, etc...). At least these
are
the two definitions of fstype that I know of. So I am still stuck at
trying
to determine how fsck automatically determines the second definition
of fstype. Remember that fsck works if I explicitly tell it to use ufs.
My
other theory is that maybe my newfs binary isn't doing it's thing. My 
understanding was that in version 5.0 ufs2 would be the default, but
it seems like my newfs uses ufs1 as it's default. This makes me wonder

if maybe other things aren't working as they should. Any ideas, leads,
thoughts, or suggestions are always appreciated... thanks again.

Dave.
