The own Maemo team helped demoting our own sessions since there was a bunch of them presented in the last moment (long story, nobody's fault). By doing that we made space to other good presentations from non-Nokians.
The schedule is a wiki, so if you have good ideas adding and not touching much what there is already in place I guess they can be still discussed.
Think though that there were other sessions demotes or rejected as well, so reopening the debate might be tricky.
On the other hand, you can always contact Marius or Igor and ask them to improvise a gathering in the community area, with plenty of tables available out of lunchtime.
