Quim Gil, Nokia Maemo Devices Open Source Advocate, has started a thread at talk.maemo.org to define the ways to contact, as well as influence the Nokia Maemo Devices Team.

He mentions several ways of doing it like actively reporting bugs (Bugzilla), proposing new ideas and solutions (Brainstorm),  rate news and blog items (News and Planet), rate and provide feedback on apps (Downloads), contact developers directly (maemo-developers mailing list and Development forum), join the discussions (Community forum and Sprints), and nominate and vote for your  Maemo Community Council candidates as they will have a direct line to Nokia.

Notice that all these channels point to maemo.org, the home of the open source Maemo community. If you are not yet a member, join now (here and here), and let your voice and ideas be heard.
