    Yep, we were going to do that, but chose to use the
    1MB region already setup for the IMMRs since its already
    marked as non-prefetchable. We were only doing reads, so
    it wasn't going to hurt anything.

    I doubt that marking one of the other BAR regions
    as non-prefetchable will give a different result.
    However, we're more than happy to double-check if
    you'd like.
