If you prefer working in bzr, it is certainly a working way. It's about the same effort as attaching a patch to a bug report (except that I can't modify the status of non-Ubuntu merge proposals).
The best/canonical way would be to supply format-patches or branches against the upstream branch, which is http://git.kernel.org/?p=linux/hotplug/udev.git in this case, and attach them to bugs or send a mail to <email address hidden>.
