Don't be so sure. Light maps can have directional informations that will be used 
to generate the shadows and the shading of the objects. This don't even take 
into acount the preshading of the objects, or the fact that sprites can include 
the shadows, as it's evident in the one showing the walking personage.
In some cases, they use light map to provide the ambient lighting and light for 
the shadows, then add environment map to complement the shading and highlights 
as well as simulating reflections.

You know you've been raytracing too long when you downloaded and printed the 
Renderman Interface documentation, so you'd have a little light reading to take 
on holiday.
