Given that the driver is clearly doing something that affects the hard
block, or triggers it, isn't the correct fix here to get the driver fixed?

This could be an issue with the BIOS's ACPI tables too; the driver may
be triggering ACPI byte-code to execute which has the side-effect of
incorrectly toggling the hard block, or perhaps there's some ACPI method
that should be being executed, but isn't.
