I've never seen a licence that includes a large part of the GPL that
wasn't the entire unmodified GPL. Copying ideas or short extracts of
text is not forbidden by copyright law.
Also, you could, if you wanted, include the entire unmodified GPL and
add an introductory section that changes the meaning or what follows.
The copyright notice at the top of the GPL doesn't say that verbatim
copies of the licence may only be made for the purpose of applying the
unmodified GPL. I don't think anyone would be well advised to do that,
however. (The extra text in /usr/src/linux/COPYING is supposed to
merely clarify the GPL.)
