FYI Brett, some Opteron systems have a BIOS option to interleave memory. If you are going to make use of NUMA, I think you want to not interleave.

I can confirm this. On my Tyan Thunder K8W 2885 (dual Opteron), I had to disable interleaving (under the Northbridge setup) before Linux recognized it as a NUMA system.
