Subject: Notify non-GPL module loading will be going away in January 2008

Numerous kernel developers feel that loading non-GPL drivers into the
kernel violates the license of the kernel and their copyright.  Because
of this, a one year notice for everyone to address any non-GPL
compatible modules has been set.
