    Exactly. It's not that we care about trying to protect a system that
    really needs to use MMCFG - once you really *really* need it, you're
    screwed if it doesn't work.

    But currently 99% of all systems will never need it, and for the broken
    platforms, that's a nice round 100%. So if we make code not use MMCFG by
    default, and you have to enable it for just those device drivers that
    really want it and care, you automatically avoid all the broken hardware,
    with no real downsides.
