[issue658] mostly fixed .. still broken for CAM :(

    I think we are good to go to make NATA the default about mid month, and
    use it in the release.  I'm confident we can track down the remaining
    PCI_MAP_FIXUP issues.  The direct AHCI support in SATA has really sold
    me... finally a disk controller standard that not only works well,
    but will probably completely replace the 30-year-old IDE cruft in
    another year or two.
