My copy of mountd(8) suggests the above lines, but then goes on to say:

-----------------------------------------------------------------------
  This example assumes your TCP wrapper library was compiled
       with options support (which I highly recommend). If it has
       been compiled without options support, you need to add the
       following    two    lines    to    /etc/hosts.allow    and
       /etc/hosts.deny, respectively:

       # hosts.allow:
       rpc.mountd : 192.168.1
       # hosts.deny
       rpc.mountd : ALL
------------------------------------------------------------------

So perhaps it is worth trying those instead.

We could, of course, be completely on the wrong track chasing after
tcpwrapper misconfigurations, it is just that that seems to be the most
common cause of failure for NFS. The other thing I've had problems with in
the past is having the wrong sort of whitespace in my exports file. (or
just a wrong exports file, but I am sure you'd have checked that first.)
