Aah, I guess we need to implement proper support for QEMU BIOS config
port ("0x510") because the dummy port is accidentally asking for a
boot menu.
If I disable boot menu support from SeaBIOS, I'm now seeing this PCI
"out of address space" error which I suppose is what Ron and John were
talking about earlier:
