I'm using the openmpi-1.1.1-5.el5.x86_64 RPM on a Scientific Linux 5

one shown below. Is there some way I can supress these, perhaps by an
appropriate entry in /etc/openmpi-mca-params.conf ?

Yes, there is a line you can add to /etc/openmpi-mca-params.conf:
btl=^openib
will tell Open MPI to use any available btls (our network transport
layer) except openib.
It works! Thanks for that :)
