Sadly this does not seem to work for me on my system:
~ # modprobe ath5k
NET: Registered protocol family 10
cfg80211: Calling CRDA to update world regulatory domain
ath5k_pci 0000:00:0c.0: registered as 'phy0'
ath5k phy0: Atheros AR5213A chip found (MAC: 0x59, PHY: 0x43)
ath5k phy0: RF5112B multiband radio found (0x36)
~ # iwconfig wlan0 mode ad-hoc
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Operation not supported.
~ # iw reg set IT
cfg80211: Calling CRDA for country: IT
~ # iwconfig wlan0 mode ad-hoc
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Operation not supported.

Ah, that is useful, but again sadly doesn't work!
~ # iw reg set GB
cfg80211: Calling CRDA for country: GB
~ # iwlist wlan0 frequency
wlan0 11 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
Channel 03 : 2.422 GHz
Channel 04 : 2.427 GHz
Channel 05 : 2.432 GHz
Channel 06 : 2.437 GHz
Channel 07 : 2.442 GHz
Channel 08 : 2.447 GHz
Channel 09 : 2.452 GHz
Channel 10 : 2.457 GHz
Channel 11 : 2.462 GHz
Current Frequency=2.412 GHz (Channel 1)
In the UK we are allowed to use Channel 13...

I have just downloaded madwifi 0.9.4+r3772.20080716 from Debian and
got that working with kernel 2.6.28, so I think I will use that for
now until ath5k matures a bit....
