And you can provide the image name on the command line, and complexity
is in Qemu, not in BIOS.

But in fact, my first idea was to read the image data from the
configuration device (which is always possible with LOGO_CMD_OFFSET),
but when I saw how it has been done in VirtualBox, I though it was a
good idea.

But I agree, it's ugly.
