Heh, good point.

An updated version is below.

Oh, and for those who have asked me how we would enforce this after this
date if this decision is made, I'd like to go on record that I will be
glad to take whatever legal means necessary to stop people from
violating this.

Someone also mentioned that we could just put a nice poem into the
kernel module image in order to be able to enforce our copyright license
in any court of law.

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.
