[gentoo-laptop] Intel 735 vs Gentoo Install Config

[John Manko <jmanko@johnmanko.com>]

I have the Gentoo Installer running on my Thinkpad Pentium M 735, and a 
few things caught my eye.  The 735 is a Pentium M 
(http://intel.com/products/processor/pentiumm/index.htm), so I selected 
Pentium-M as the architecture type on the gcc config tab. I was 
wondering about the discrepancy.

TheCXXFLAGS value doesn't seem customizeable (CFLAGS is set to the 
values I set). And further down is what is configured during the 
Install's kernel config (MPENTIUM4 is chosen instead of MPENTIUMM):
