Yep, I think we can do something along the lines of what hpa suggested:

* put a kvm_guest.config in arch/x86/configs/

* teach scripts/config/ to parse it and do set_var() for each line in
there.

* yes "" | make oldconfig - because we want to use the current config
as a base.

I think this is the easiest and cleanest of them all.
