What symbols?

sudo rmmod ath5k
sudo dmesg -c > /dev/null
sudo modprobe ath5k
sudo dmesg -c

Ahh this one.. this is the 2 character module parameter you can pass
to cfg80211 upon load and this is available only when
CONFIG_WIRELESS_OLD_REGULATORY is enabled.

I still don't see why you are seeing this, as your modprobe command
did not pass any module parameter options.. do you have some options
for cfg8021 in your distribution place for them on /etc/ somewhere?

I am in hopes distributions can start packaging iw and crda sooner
rather than later, if not we will have to consider pushing the removal
of this option for until 2.6.30 and also set it to default in 2.6.28
(?). I'd hate to see this but I guess this is reasonable since not
even NM is yet asking yet cfg80211 to set the regulatory domain to a
specific country.
