You do need a separate driver because you've got no guarantee that the PATA chip you are driving has a non-ACPI driver of any kind. For the Nvidia PATA Tejun may be right, although it'll be very risky since you've no idea what the ACPI methods decide to reconfigure the moment you start touching the chip via ACPI and directly.
