I didn't try MVAPICH, but I had no luck getting Open MPI 1.0.1 to work
with the RHEL4 U3 OpenIB code.

The RHEL4 U3 relnotes are pretty clear that its included OpenIB is a
technology preview not for production environments, and the APIs are
subject to change (which they already did comparing RHEL4 U3 to OF 1.0).

I think you are much better off trying the OF 1.0 code.
