I've now modified kerneloops to add support for writing an apport report in
addition to the standard kerneloops.org submission.  This will allow us to
participate in the kerneloops.org statistical measurement, and also receive
semi-automatic bug reports for oopses which occur in an Ubuntu release which
is still under development.

I spoke to Arjan about the patch, and he indicated he was willing to accept

Amit discussed this with Arjan at some length at the Linux Plumbers
Conference, and the conclusion seems to be that he wants a way to identify
Ubuntu kernels based on the version number, and confirmation that we'll
address the top issues which come up (and not let them languish), which is
already our practice.
