This is a Core 2 Duo CPU, so my CPU vendor is Intel. I assume that the relevant people are already reading this, no?
I'm not sure what I'm supposed to do? Write an Email to Intel support, referencing this thread? Doesn't anyone here already know the right people at Intel who could actually do something about this. I think that would be more useful since I doubt an email to Intel support would reach those people...
Regards, Mika
