	This is a common misconception. The GPL *never* bings the recipient of a
GPL'd work until and unless he agrees to it. You can find this made quite
clear on the FSF's web site.

	The claim here is not that one way to make an NE2000 work with Linux 2.6 is
owned but that *every* way to do that is owned. This is impossible under
copyright. You can certainly own one specific way to make an NE2000 work
with linux 2.6 (that would be a copyrighted driver), but you cannot use
copyright to prevent anyone from implementing a particular function.

	It doesn't matter. You cannot protect a function with copyright. If there
is only one practical way to get a particular function, nobody can use
copyright to own it. Read Lexmark v. Static Controls or goole for "copyright
lock out".

	You cannot lock someone out from basing their think on your thing, if that
is the only practical way to express a particular idea. See Lexmark v.
Static Controls, among other cases.

	Huh? I'm not changing anything. And I'm not talking about any rights
received with the GPL, I'm talking about rights granted by law under first
sale and scenes a faire.
