Using osgdem, I would like to create a simple terrain tile that always

Have your tried deriving your class LightMoveCallback from osg::NodeCallback
instead of osg::StateAttribute::Callback to see if the callback gets called?
Just a thought...

Most of the examples I've seen, update the position in an animation using

I believe osgdem is part of VPB now. When you build VPB, it compiles to
