Thanks for reporting that.
I've just confirmed that linux-2.6.11-rc3 xfs uses the same number.
With the fix below, I get this:

    $ ./stat --format=%T -f /tmp/mnt; echo
    xfs

Here's the patch:

        * src/stat.c (human_fstype): Add case/definition for S_MAGIC_XFS
        so that file systems of type `xfs' are recognized as such.
        * src/fs.h: Regenerate.
        Reported by Bernd Eckenfels.
