Odd .. small update.  I just noticed that parted was wrong, too!  I don't
normally use it, but I had erroneously assumed that parted and gparted
shared the same code and would give the same results.  The graphical
gparted and the gnome "Disks" tool both show the same output as blkid,
which is showing what the kernel shows.  Everything else is wrong.

How can this be?
