And some licenses require that the text of the license be included in
the distributed work (the GPL is a good example of this), and require
at least some immutable text.

Some people have been claiming that these licenses if they don't
allow themselves to be modified conflict with the DFSG on this basis.
Typically they are explicitly claiming that the GPL is an example of a
license disallowed by the DFSG.

I agree that the DFSG requires that it be possible to make and
distribute some derived works based on the original.

No, I would not.

I'd want to examine it to determine the kernel interfaces it relies on
and write something else which uses those same interfaces.

The key issue, in this example, is the quality of information provided
for this task.

In the context of the DFSG, there have been a number of posts made by
others (some to debian-legal) which conflict with your point of view.

And that's the context in which I've been talking.
