They have not changed in any way, however there is a patchset proposed currently to change how NUMA works a bit. Unclear if it will change this situation.
Would that be a mysql or linux kernel patch (assume the latter)? Also want to echo xxjaba's comment further down - thanks for doing the work on that post, it was really enlightening!
Yes, a Linux kernel patch. I've got a lot of ideas on NUMA optimization for MySQL directly though, so keep an eye out for that, perhaps some time this year.

Interesting read. Does anyone know if things have improved/changed significantly since the article was posted (Sep 2010)?
