Bug Description
The iwl3945 driver in Intrepid doesn't appear to see !US wireless channels, even on a UK laptop. My home network is on channel 13 and completely open, but Intrepid couldn't find it until I forced it back to channel 11. Hardy on the same hardware found and used the wireless on channel 13 just fine.

In order to use non-US wireless channels, add the following to /etc/modprobe.
options cfg80211 ieee80211_regdom=EU
Note that if you are using a driver from the linux-backport modules you would need to add the followng to /etc/modprobe.
options lbm_cw_cfg80211 ieee80211_regdom=EU
