[CentOS] A little more info

[Sam Drinkard]

I forgot to mention this is an x86_64 machine.  Sometime somewhere back 
several months ago, the centos plus kernel got installed, and I didn't 
notice it until just recently.  It's not in use.  I understand there are 
some i386 packages already installed, and at one point, I thought I had 
set yum up to only pull down the x8_64 packages, but I suppose something 
got changed in the yum.repos.d files somewhere along the way.
