FWIW (and google) I have just encountered this problem on 2.6.16.9 server.
My error message with the NFS mount failing was:
mount teak:/media /mnt/test
mount: teak:/media: can't read superblock
teak:~# ll /dev/media*
brw-rw---- 1 root disk 254, 8128 2006-07-18 18:39 /dev/media

I rebooted to use /dev/md_d0 and /dev/md_d0p1 and it's fine.
