This is where we really need the ACPI maintainers to explain the
general policy for dealing with firmware updates.

I would assume that adding the feature in a later firmware version
is a compatible change, and the feature is non-essential (the
device will work fine with the generic SATA driver, except
the LEDs don't blink), so it's not a big deal, it's just what
you get for having the firmware shipped before the driver is
reviewed (don't do that).

Agreed, the driver should have been reviewed earlier. And now changes in firmware will also require
them changing other OSes drivers.

Can you explain that? I would expect the addition of some AML methods
to be a compatible change.
