Exactly what I was looking for. I didn't care as much about the  
specific control as I did grokking the methodology. I was just going  
down the list: map.addControl(LayerSwitcher), map.addControl 
(OverviewMap), etc. and ZoomToMaxExtent didn't seem to work as the  
others did.

So, (warning: gross generalization ahead) should all controls go in a  
Panel?

BTW, keep your eyes on http://trimet.org. An antiquated ESRI  
interactive map is on its way out, being replaced by a full OSS  
stack: GeoServer, OpenLayers, TileCache, PostGIS, et al. I'll send an  
announcement to the list when it goes live.
