Patch applied cleanly and works for

ath0 at pci0:3:0:0:	class=0x020000 card=0x058a1014 chip=0x1014168c rev=0x01
hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'AR5212 Atheros AR5212 802.11abg wireless'
    class      = network
    subclass   = ethernet

ath0: <Atheros 5212> mem 0xedf00000-0xedf0ffff irq 17 at device 0.0 on
pci3
ath0: mac 10.3 phy 6.1 radio 10.2

My -STABLE is of February 5, 2009 about 7AM EST.

I build wireless stuff as modules and load them manually.

If it is of any value, I am using WPA-PSK.

If there is any particular testing that I can perform, or any additional
information that I can provide, please, let me know and I will be happy
to oblige.

Thank you very much for your work.
