If you can't physically have an x86 PC without a keyboard controller I'm not sure it makes any sense for QEMU's PC model to be instantiated without one. This makes sense at the moment since -device really only works for pluggable buses anyway, so there's no way for a management stack to provide anything that's really an integrated part of the main system if we don't always create it. I know people have tossed around the idea of being able to create an entire board model from configfile and command line; however we don't have that today... -- PMM
