While that's working in this case, it's definitely not how it was meant to be. 
My initial patch was missing the inclusion of the x and y offsets. This 
version works with the gamearea located at any position:

 void GameDisplay::resize_game_area (int w, int h) 
{
    DisplayEngine *e = get_engine();
    int neww = w * e->get_tilew();
    int newh = h * e->get_tileh();

    const video::VMInfo *vidinfo = video::GetInfo();

    int screenw = vidinfo->gamearea.w;
    int screenh = vidinfo->gamearea.h;

    if (neww > screenw || newh > screenh) {
        enigma::Log << "Illegal screen size ("<< neww << "," << newh
                    << "): larger than physical display\n";
        return;
    }
    Rect r (vidinfo->gamearea.x + (screenw-neww)/2, 
            vidinfo->gamearea.y + (screenh-newh)/2, neww, newh);

    e->set_screen_area (r);
    follow_center();
}
