I prefer using a different Config file to patching the Config file.  I think
it makes it a cleaner design.  It also makes it so that the ROM size doesn't
increase unless you use a larger payload.  I know that's less important for
QEMU, but...

See the Tyan boards for examples.  They have Config.lb and Config-lab.lb for
larger payloads.
