Indeed you have it right.  In any case, I figured out that I cannot 
easily disable IPv6 because it causes the heavily hacked-up EL6 kernel 
to fail to build.

kernel-thinclient.i686 is now in the Private Beta repo.  It enables NBD, 
disables PAE, and shrinks the initramfs size from 16.7MB to 13.8MB.  I 
think I can shrink the initramfs size more not by excluding more modules 
from the kernel build, but rather tweaking dracut's configuration that 
is including so many rarely needed kernel modules just-in-case they 
might be needed to boot something.
