I've cloned the git like described on: 
http://wireless.kernel.org/en/developers/Regulatory
and executed make install in that dir.

The debug info indeed changed to 160MHz bandwidth, see my debug output.
sudo iw reg set BE doesn't seem to work anymore... but still works from 
hostapd config.

Does this look ok to you, as I am unable to observe the AP from another 
similar machine.
