I agree. Linus' comments on the matter, except of course his original
exception for userspace which has been there since 1993, are an
irrelevant _interpretation_.

All that is relevant is the meaning of the original licence.

This statement is in conflict with the presence of the exception for
userspace which precedes the text of the GPL in the Linux COPYING file.

The presence of the exception makes it clear that, without such
exception, userspace would have been considered to be a derived work in
the terminology of the original licence. Otherwise, the exception would
of course have been redundant.

If userspace would be considered a derived work without explicit
exception, then so are kernel modules. They have no such explicit
exception, and are hence not permitted.

I'll grant you that Linus' witterings in public on the matter would
probably prevent him _personally_ from bringing suit against a
distributor of binary-only modules, on the principle of equitable
estoppel.

That doesn't stop me or anyone else from doing so though.
