This is what the Windows driver does; not yet implemented in Linux. I'd like to document the different variants of this card on the wiki. Can you send me the output of lspci -vvnn for your variant? If you have Windows, can you also send me some RegSpy states similar to the ones I'm attaching to this mail? Regards JD
