Where is the bulk of resources going to, to which services? Have you tried to contact an organization such as Ibiblio to host the content (at least the source and binaries of the repositories). Or adding local mirrors? You can also check, which mirror sponsors are helping out organizations such as Debian and Ubuntu (I know for a fact my ISP sponsors them). You'll need to be specific in your request though. Maemo is non-profit and deserve aid from universities etc IMO. Just generally, decentralization helps to cut costs. Or maybe add banners and allow a premium subscription (could be a possible plan B).

For the record I'm not trying to downplay what you folks are doing and I'm not even using Maemo myself anymore (God, what happened here?!) just trying to help.
