When I wrote this I posted the patch to lkml [0] for wider review and
naturally I got the same reaction from folks. I wrote it originally
with the goal to do something distro-agnostic and in fact it is, its
just that I haven't figured out a quick way to make this work across
the board.

Well kernel.org does not have already built kernels. Ubuntu's PPA
kernels *are* vanilla kernels, in fact that is why they were put up,
they are guaranteed to be built on vanilla kernels. We couldn't get a
more generic approach then. The only thing though is -- the PPA
kernels obviously have the kernels integrated on .debs. There are a
few options here:

  1) If Ubuntu can dpkg -x the kernels for us onto tarballs that'd be swell
  2) We could write our own script to do this with C code that does
the dpkg -x for us

There are ways to do 2) suggested in the thread above.

That'd be amazing!
