Fan resume handling - ACPI resume callbacks?

I'm trying to implement resume support for the fan driver. From what I can tell through experimentation, the easiest solution is to check if the fan claims to be switched on, and if so to switch it off and on again. However, my resume callback never seems to be called. I've got

static struct acpi_driver acpi_fan_driver = {

        .name =         ACPI_FAN_DRIVER_NAME,
        .class =        ACPI_FAN_CLASS,
        .ids =          ACPI_FAN_HID,
        .ops =          {
                                .add =          acpi_fan_add,
                                .remove =       acpi_fan_remove,
                                .resume =       acpi_fan_resume,
                        },
};

but adding printks to acpi_fan_resume doesn't seem to result in anything in the kernel logs. Is this stuff supposed to work?
