They are both still present in ompi/mca/mtl/
I have access to a system w/ QLogic HCAs w/ PSM and have verified that I can:
$ mpirun -mca btl sm,self -np 2 -host n15,n16 -mca mtl psm examples/ring_c
I have an x86 (32-bit) system w/ MX headers and libs that I have successfully configured and built on.
However, I no longer have Myrinet h/w (well, there is some in a box in the machine room but my dedication to Open MPI rc testing doesn't extend far enough to install the h/w).
