Your best option is to change the Atheros card EEPROM to match the device and vendor id of your wpi card. Then you also need to change the ath driver to attach to that device id.

Yes, but it still sucks. And I actually have no idea how to flash the
ath device. All the instructions on this I have found use Linux.

I'd prefer to flash the notebook BIOS, but I have no way to defeat
its evil compression.

Nay, this is my goodbye to Intel brand wireless. I always thought
wpa_supplicant was to blame for unreliable connections, but it
all just works with the Atheros hardware.
