The relevant limit in Canada and the USA appears to be 1 W.  
(For both Debian and Windows!) 

A laptop marketed in Canada or the USA might be illegal for 
use in Europe, even if Debian is replaced with LiMux?

Power density should be more pertinent to interference than 
total radiated power.  Location should also be pertinent.  
In an urban location, the neighbour can be a few m away whereas 
in a rural location the neighbour can be half a km away.  
But reference to density and location might introduce unaccepable 

Thanks for the replies,          ... Peter E.
