  I'm installing Gentoo on a brand new toy I just got myself.  Here are
the choices from "make menuconfig".  Is "Core 2/newer Xeon" correct?

 ( ) Opteron/Athlon64/Hammer/K8
 ( ) Intel P4 / older Netburst based Xeon
 (X) Core 2/newer Xeon
 ( ) Intel Atom
 ( ) Generic-x86-64

  Here's the listing for one of the cores from /proc/cpuinfo

Y U NO read help of that option? It's clearly specified there that
newer Xeons have family 6 and older ones have 15.
So, your choice is right.

You can also use this patch which adds support for modern (>=gcc-4.6) CPU
options to the kernel:
http://www.linuxforge.net/linux/kernel/kernel-30rc5-gcc46-0.patch -- you can
get Intel Core i7 and Intel Core i7 AVX choices in your kernel.
