    The problem is we can't detect AMD76x IDE and thus the prefetch into
    I/O space bug until we've done memory setup. What probably should occur
    is we grab the 636-640K page if it would otherwise be free, and then
    free it after pci quirk handling.

    Another approach would be to write a replacement ide_build_sglist for
    the AMD76x which bounces the problem page.
