ok, so the problem is in either mkfs or xfs_db.  after mkfs, run:

# od -c -N 8 /dev/hda9
0000000   X   F   S   B  \0  \0 020  \0

you should see exactly that (the second 4 are the blocksize).
if you do, its an xfs_db problem.  if not, its a mkfs problem.
lemme know.  (at the same time, could you send the unfiltered
"xfs_db -r -c sb -c p /dev/hda9" output also?)
