    Looks like this is something the kernel is assigning to it. It *does*
    get marked reserved:

    > [ 0.000000] #6 [000009ec00 - 00000f0000] BIOS reserved

    ... but that doesn't seem to keep the PCI code from assigning anything
    there. This is a Very Bad thing in general... if we're assigning
    devices to areas marked reserved, we have a huge problem.
