Your version of automount is still old. Please grab the latest src.rpm from f8, or grab the latest from Ian's git repo. When you do that, you'll find that the rpc_ping code will not be executed unless an entry is a replicated server entry. If you still timeout on the mounts, you can experiment with the "retry" nfs mount option.
