Actually, I suspect Daniel has read it, and is probably referring to
another facet of the license: distribution of two things together does
*not* imply that those two things have to both be GPLv2's.
The GPLv2 explicitly mentions "mere aggregation". Strictly speaking, it
doesn't even *have* to mention it, since it does mention in other places
that it only covers "derived work", and "derivation" has nothing to do
with "distributing two things together". But it's a good clarification.
So you guys are *both* right, for different cases!
The issue is simply what you mean by "part of the whole"? If you mean
"part of the whole kernel distribution", then yes, the kernel is one work,
and it is, in its entirety, under the GPLv2. But if the "part of the
whole" is about something like a DVD with the whole being a collection of
"mere aggregation", the licenses do not necessarily meld together.
Let's say that you're a Linux vendor, and you distribute a DVD with both
the Linux kernel binary (and all the normal modules that go with it, that
obviously are "part of the whole kernel") *and* say the NVidia proprietary
kernel module.
Is that the *only* way to read things? No. It's a matter of
interpretation, and which "whole" you are talking about. The whole
aggregation, or the whole program?
And is the NVidia module a "derived work" or not? That's a gray area, and
that's really what it hinges on. I personally think it's not, but I know
others think it is.
Which is why I think you're both *potentially* right. Which one of you is
*actually* right will depend on the exact circumstances ;)
