From my point of view the option of using an external hwloc for OMPI
eliminates the need to be overly concerned about back-ports for
OMPI-1.5. If I really need hwloc w/ my RHL8 (dual-socket/single-core)
systems, then I'll build hwloc-1.3.x (w/ patches if needed) and point my
OMPI build at it.
I have no opinion on what belongs in OMPI 1.6 or 1.7.

Is hwloc 1.3.x a good candidate here? As Paul noted, without some of the recent fixes, OMPI 1.5.5 won't run on older Linuxes (e.g., Fedora 8).
