The kernel updates make the NUMA code dual-core aware, which apparently
makes a big difference in some cases but not in others. It makes some
sense, since multi-processor multi-core machines will have two different
types of non-locality instead of just one that need to be managed. Prior to
the v2.6.12 patches, a dual-core dual-proc machine was viewed as a quad-proc
machine.
The closest thing to a supported v2.6.12 kernel that I know of is FC4, which
is not really supported in the enterprise sense of course.
