That was intentional because a node is defined as an area of memory and an area of memory without memory didn't seem to make sense. I still don't think it does. Instead the CPUs are assigned to nearby nodes. Back then the generic code also couldn't deal with them at all, so you might well run into more problems. -Andi -- ak@linux.intel.com -- Speaking for myself only.
