    Excellent idea! I'd love to have this in RHEL5u1, because that would make
    that distro boot on certain machines that have more memory than is supported
    without an iommu driver. The problem we have is that when you simply
    say mem=1G but all of the first gigabyte is on the first node, you end
    up with a memoryless node, which is not supported.

    Unfortunately, it comes too late for me now, as all new distros already boot
    on Cell machines that need an IOMMU.
