Well, Community could say "no" in the referendum or vote something idiotic by 2/3 majority of votes in General Assembly, which Board would be obliged to commit or step down. Then, it would probably end up with "winding down", as no one would like to take legal responsibility for organization working wrong way (if community would deny organizational changes in referendum), or to do something illegal (if such thing would be enforced on Board by 2/3 votes).

In such case, either new Board is elected and performs what Community decided - taking legal risk, that former Board wasn't willing to take - or, if Community demands something, but don't have people willing to do it (no candidates), organization would just get disbanded.

Summing it up - Board is not a bunch of "overlords". General Assembly is (aka, users from Community that are actively interested in deciding future of Maemo), and it just delegates representing them to Board. General Assembly can, always, change things by majority of votes (or choosing different Board).
