Normal mapping does not appear to be a first class citizen in FBX SDK and Maya at this point. I hope that Autodesk addresses this since normal mapping is an integral part of modern real time rendering.
There really should be a separate channel for bump maps, tangent space normal maps and object space normal maps. In my app I need both object space normals and tangent space normals for meshes.
This should also be exposed in Maya, too, not just a bump specification that you can override with a normal map selection.
When using the normal map channel, you will run into the problem that I had here:

the GetNormal property is not accessible.
