Good question. :)  This came in as a feature request from a RH customer,
and it took a while to understand that this was the feature they wanted.
 My only guess is the user is someone else than the administrator, so
they cannot control the QEMU command-line.

I'm not sure how much of this code is used by Coreboot, but I figured
this would be somewhat useful on bare-metal systems too.
