I was first wondering if for some reason defaulting/forcing PCI to always
be configured for 44x was intentional.  I was second reporting the fact
that if a change is made to not configure PCI for 44x, the kernel will not
compile.

Yes. I think it's quite obvious from the way it's configured in 
Konfig.

Well, I don't follow you here. You made the wrong change and report 
here that it broke the build. How is this interesting?

Your report looked as you discovered a bug, when in fact you broke the 
build yourself.

And again, if disabling PCI is important to you you are welcome to 
submit patches instead of sending misleading e-mails to this list.
