Nice new feature ... on Leopard going to the /net directory behaves the same as with Solaris..
$ cd /net/hostname.domain/path/to/nfs/share
To be ale to mount all nfs mounts properly I had to add the 'resvport' option (see mount_nfs(8)) to /etc/auto_master
$ cat /etc/auto_master
#
# Automounter master map
#
+auto_master # Use directory service
/net -hosts -nobrowse,nosuid,resvport
/home auto_home -nobrowse
/Network/Servers -fstab
/- -static
