Crap, I can't find the article where Intel was comparing the Opterons to 
the Xeons that I was reading last night. It mentioned what the Intel 
guys used for GCC with -march on a Core 2 Duo system.

However, I did find a Gentoo Wiki page where it says that safe CFLAGS / 
CPUTYPE values for EM64T CPUs is nocona: 
<http://gentoo-wiki.com/Safe_Cflags#Xeon_w.2FEM64T_.28Intel.29_.28also_Pentium_4_P6xx.29>. 
The only thing is that they use gcc-3.4 by default as well as gcc-4.1 / 
gcc-4.2, so processor support may be better with the later versions of gcc.
