I analyze Lee Schermerhorn's migrate memory on cpu migration patches
(http://free.linux.hp.com/~lts/Patches/PageMigration/). I think that Lee
Schermerhorn add similar functionalities to the kernel. He called the
"affinity-on-next-touch" functionality "migrate_on_fault" and uses in his
patches the normal NUMA memory policies. Therefore, his solution fits better
to the Linux kernel. I tested his patches with our test applications and got
nearly the same performance results. 

I found only patches for the kernel 2.6.25-rc2-mm1. Does someone develop
these patches further?
