This is a long-awaited change. Let's not be afraid of it. It will likely 
prove just as successful as moving graphics drivers from the base system 
to the ports tree. Now, the transition would be much less painful thanks 
to the availability of the new kmod repositories.

Many thanks for the WiFi improvements, for the heads up, and for 
inquiring in the community !
