There are two issues. Atmel don't currently give me permission to
distribute their firmware so I need them to fix that. The keyspan 
wording is one way to do it.

Then, as you say, I need to know if the kernel developers have given
permission to distribute a work which combines Atmel's blob with
their source.[1]

If this was code which was linked into the kernel the answer would
clearly be no. Since it is not linked to the kernel, and doesn't
even run on the same processor as the kernel, the answer is not clear,
at least to me.

Maybe we need Linus to pronounce, or RMS. Existing practice has several
drivers with  firmware blobs[2]. What is the status of those? Am I
asking Questions Which Should Not Be Asked?

Simon.

[1] and though I'm not (yet) a holder of copyright on part of the Linux
kernel source, I do distribute other software under the GPL so these are
my rights we're talking about, too.
