Just

options ATH_DEBUG

in my $KERNCONF and I built the ath and ath_pci modules.

Yup:

ath0_at_pci0:2:0:0:        class=0x028000 card=0x10891a3b chip=0x002b168c
rev=0x01 hdr=0x00
    vendor     = 'Atheros Communications Inc.'
    device     = 'AR9285 Wireless Network Adapter (PCI-Express)'
    class      = network

Thanks!
