Not comprehensive (I have no idea about Harmattan for instance), but here's what I can think of: SDK repository non-free parts (eg http://repository.maemo.org/dists/diablo/sdk/non-free/) SDK "nokia-binaries" for Bora/Chinook/Diablo (eg http://repository.maemo.org/stable/d...aries_4.1.2.sh and similar). Firmware images, flashers, SDK rootstraps and nokia-binaries for other releases (http://tablets-dev.nokia.com/) http://catalogue.tableteer.nokia.com/ (most importantly the non-listable updates trees). The Fremantle equivalent is hosted somewhere else but I don't remember the URL, see /etc/apt/sources.list.d/hildon-application-manager.list on an N900. There's also the non-free parts of extras, but those are generally not (C) Nokia. You can use something like Code: wget -q -O- http://repository.maemo.org/extras/dists/diablo/non-free/binary-armel/Packages.gz | zegrep '^(Package|Maintainer):' to extract the maintainer email addresses though.
