Just an update: it appears that once your 10GBE card begins to work on your Hackintosh, that occurs only aft erApple does something to the card, and the native Windows drivers stop working until you install the Boot Camp Windows drivers for the card. So, I've attached the Boot Camp Windows drivers.
It's a pretty easy install in Windows. But you need these drivers after the card starts to work in the Mac side. If you only use the Mac side, and you never boot into Windows, you would never know (or even care) what Apple does to the card.
