The texcoords for the subdivision sphere are messed up, if you want to
texture a sphere, try the LatLongSphere or a torus (my favorite ;).

Nope, just adding them is all you need to do, see
testVertexProgramRender.cpp. 

Are you sure the loading succeeded? If not, the ProgramChunk should
print a warning.
