Those are only used when the driver is explicitly loaded with use_msr=1. The default is to use PCI config space/VSA.
In any case I have yet to see a CS5536 system whose BIOS sets the cable detection bit. If that's the problem I guess we could add a quirk flag to override the (lack of) BIOS setting.
