Apparently Core 2 is similar to the Coppermine T in some ways
(such as netburst) but I think that its new as well since it's the
model for quads, i7's etc;

Compiled a generic for i686 and it worked perfectly with both
processors, but then my old gentoo instincts kicked in and I compiled
two different versions.
