Am I right in thinking that -display none vs -nographic has *no* effect
on guest machine ABI ? I think we're safe based on my reading of it,
particularly since we use -nodefaults and -nodefconfig, but want to confirm
there's no edge case i'm not aware of.
It changes one fw_cfg field from 0 to 1, but only OpenBIOS looks at it
right now.
