    Jeff Garzik intends to add a passthru ioctl to libata, specifically for
    applications like smartmontools. As soon as he's done this, we'll add
    another '-d sata' device type to utilize that ioctl().

    I don't know the answer but suspect that the scsi layer can handle this
    'as is'. In fact the 3ware support in smartmontools passes all commands
    through the scsi layer.

    I appreciate the offer to act as a tester -- you'll probably hear from me
    when this work is in progress, to take you up on it.
