NFSv3 over TCP is the default for most modern distros (obviously this 
rules out your setup ;).  I honestly don't remember if it was supported in 
RH9 (I think it was, but that was many moons ago) but it'd be easy to 
test.  Just add 'tcp' to the mount options in /etc/fstab and try the 
mount.  If it's not supported, it won't work.
