If you are the only author of the stuff you want to backport, I believe you do not need to ask any permission from anyone. Donating your own work to a FSF project does not prevent you from contributing it to a different project, even under a different license (IIUC, for example the go front-end works this way too). Of course, you must not include anybody else's substantial piece in the backport. Martin
