Ok, I tried to set via the tunable api kenv through loader, but this is the
result:

# ifconfig ath0
ifconfig: interface ath0 does not exist
# ifconfig ath1
ifconfig: interface ath1 does not exist

ath0: <Atheros 5212> mem 0x80000000-0x8000ffff irq 12 at device 13.0 on pci0
ath0: unable to collect channel list from hal; regdomain likely 96 country
code
203
device_attach: ath0 attach returned 22

ath1: <Atheros 5212> mem 0x800c0000-0x800cffff irq 9 at device 17.0 on pci0
ath1: unable to collect channel list from hal; regdomain likely 96 country

device_attach: ath1 attach returned 22
