Wait, what? The only "default" device we have on s390 is virtio-console - and 
that's basically the same as having VGA output on x86 enabled by default, no?

But either way, I agree that we should make things easy for 99% of the users. 
And taking incremental improvements is useful too. pc.c as it is right now can 
only be improved, no matter what you do with it.
