I try to sort of answer the questions/things from both emails you sent, I hope I
don't get too confusing. ;)

For Lucid: When Len has submitted everything to stable, this will automatically
drop into Lucid through Greg dumping it out. Technically you would not even need
a launchpad bug for that. But its needed for things that should go into Karmic.

For Karmic: Now as upstream 2.6.31.y is not updated anymore, everything that
should go into that needs a LP bug. The simplest thing for us is if you can mail
the numbers here. Then there is usually a review and based on that it will make
its way or not. There is a short Doc which hopefully helps a bit on what usually
gets taken or not (https://wiki.ubuntu.com/KernelTeam/KernelUpdates).
Enabling HW could be a reason but if the patch looks complicated its rather not
done. But you said your main interest for the second part is Lucid anyways.

So Lucid should get it soonish and Karmic might get the first patch if you send
the bug number (best send both, then we track things in there).

Thanks a lot,
