    Thanks for clarifying Bill, and sorry Alan. ata_piix does indeed work
    correctly. The help text is a bit confusing:

    config ATA_PIIX
    tristate "Intel PIIX/ICH SATA support"
    depends on PCI
    help
    This option enables support for ICH5/6/7/8 Serial ATA.
    If PATA support was enabled previously, this enables
    support for select Intel PIIX/ICH PATA host controllers.

    "Enabled previously"?
