Not directly relevant, but I do find that the utils/lstopo
command which comes as part of hwloc from the Open-MPI
project is extremely useful for visualising the NUMA
architecture of a system (and the 1.3 pre-releases include
libpci support so you can see where PCI slots, NIC's, disks
etc hang off too).

http://www.open-mpi.org/projects/hwloc/

It can do text dumps, PNG's, XML, etc.  If you've got it
compiled with X11 support then it'll throw up a window
showing the graphical layout.

cheers,
Chris
