    Yeah, if that's the goal, skip all the mini-BIOS junk and just rely on a
    PV kernel in the guest.

    I think a mini userspace that assumes that we can change the guest
    kernel and avoids having a ton of complexity to do things like CMOS
    emulation would be a really interesting thing to do.
