I think you have to assume that doing this is beyond most people.  Further, as
a distribution we would prefer people didn't raise bugs against kernels that
we didn't build.

That's the problem is right there.  AIUI, we *don't* want to set up a third
party signing process.  As I said, it potentially comes with lawyers attached.

There's more to it than that, but I feel I should discuss it with our legal
dept. before airing it here.
