@dred, totally different chipset, I would recommend you to convince Zephyroth to include this in his next PPF. If you find any working kexts, provide them to him.

found a couple of resources that may help you:

I don't know what the exact model of your Atheros chipset, but the resources I provided above may give you an idea.
Working kexts are there as well including a configuration guide, etc. Worth checking out.
