    That is the whole point of this, yes. Furthermore, it is expected that
    we *also* would be able to set platform flags based on early probes.

    Not entirely surprising, since this stuff is more or less randomly
    sprinkled through the existing code. We have a huge bunch of legacy
    code and yes, it needs cleanup.

    This is a huge opportunity, of course, but it's going to be a lot of
    work. A lot of this is likely to overlap directly with the needs of
    Xen, too.
