Hmm, yes of course. This of course breaks on our slave servers when

/sys on some cores..

Hold on, are you saying you have cores with an invisible NB? How does
that even work? Or is it only invisible to sw?

only invisible to the kernel because the multi-pci-domains isn't working pre 3.9 on our architecture.
