Atheros with the 2 radios mini-pCI card under 5.2?

I have one of these min-PCI ar-5212A Atheros cards,
with both the A and B/G on the same card.


In 5.2, it shows up as just a single ath0 device.  Is there 
a way to use both devices at the same time?

There's 4 jacks on the card.  2 labeled A, 2 labeled G.

Thanks in advance for your time.
