That's what I was hoping to do with this driver. There are still boards out there equipped with uPD720200/uPD720200A that have older firmware. If you don't have the latest firmware (which is also from 2012), then PME and a few other things will not work (so resume from D3 does not work for example). thanks, -- heikki
