Yes, I think so. In fact some people use 1.4.x NFS servers right now  
and the most
annoying problem so far is speed issue tracked in bug 13371.

Make sure you have enough bus bandwidth on the gateway for both  
connections.
If you plan to run two separate instances of NFS servers to same  
lustre FS on same
gateways, you need to come up with some way for sun25k (I presume it  
is single
machine with many CPUs?) to use both NFS servers for same export.

I do not know. I'm not even sure what IB loadbalancing is.
