OS X 10.7.4 Wi-Fi 802.11d network interface country code switching
Not that I am aware of (Believe me I've looked). I had this issue too (See my blog post here: http://jeff-with-a-g.blogspot.com.au/2012/04/5ghz-wifi-on-your-mac-got-you-down.html). 

In the end I had to choose a channel that worked in all of the regulatory domains that my neighbours' wireless access points were broadcasting. That may be a bit trickier in Europe given the smaller number of channels available.

This doesn't seem to affect Macs running Snow Leopard so I guess it's an issue with Lion. Maybe Mountain Lion will provide a fix.
