The HCL over on OSX86project doesnt look to promising for your card. I did find this thread about inserting your device/vendor ID numbers into an existing kext but It didn't look like they had any success.

When I start looking for a driver I begin with finding out:
1. Manufacturer Name
2. Model Number
3. Version
5. Vendor ID
6. Device ID

I would download DPCI Manager here: http://duddie.kazzuya.com/proj/DPCIManager_01.zip This tool allows you to find the Vendor & Device IDs for your Atheros card

It will show you something like this:



For example the numbers on the left in the first column are the Vendor IDs and the numbers on the right in the first column are the Device ID. Find your graphics card's vendor & device IDs. That will be a start.
