Can you run mount under strace -F -eexecve and see if the arguments it
passes to mount.nfs are different when you add the -v?  If not then the
bug is in mount.nfs rather than mount.

  mount.nfs fails stating incorrect mount option but succeeds if -v
  option is used

Bug description:
  Binary package hint: mount

  with /etc/fstab containing;

  n2:/db /db nfs auto,nfsvers=3   0 0

  OR containing

  n2:/db /db nfs auto     0 0

  # mount /db

  fails with message "mount.nfs: an incorrect mount option was
  specified"

  # mount n2:/db /db

  also fails with the same message

  BUT the following succeeds despite the "Operation not supported"
  message

  # mount n2:/db /db -v
  mount: no type was given - I'll assume nfs because of the colon
  mount.nfs: timeout set for Thu Mar 11 15:14:50 2010
  mount.nfs: text-based options: 'addr=63.227.222.65'
  mount.nfs: mount(2): Operation not supported
  mount.nfs: trying 63.227.222.65 prog 100003 vers 3 prot UDP port 2049
  mount.nfs: trying 63.227.222.65 prog 100005 vers 3 prot UDP port 32767
  mount.nfs: text-based options (retry): 'addr=63.227.222.65,vers=3,proto=udp,mountvers=3,mountproto=udp,mountport=32767'
  n2:/db on /db type nfs (rw)

  This system in question dual boots 10.04 and 8.04; under 8.04 ALL of
  the above succeeds without error messages.

  This error is preventing NFS mounts in /etc/fstab; without a
  workaround or fix this prevents any deployment of Ubuntu 10.04 for us.
