I don’t consider this to be the best way (I’d prefer direct manipulation of the fcurve data), but for now, this works. Note that the objects being keyframed mus be in currently visible layers.

To expand on taniwha’s method: you can also use the keyframe_insert-method of StructRNA to create new keyframes for properties. I this this is less arcane than relying on the type-parameter in the keyframe_insert_menu-method

@Spyke

sphere = bpy.data.objects['Cube']
scene = bpy.data.scenes[0]

def layer_set(frame, layer):
    # Move to the correct frame
    scene.set_frame(frame)
    # Set the objects visibility in the layer
    sphere.layers[1] = layer
    # Set the current status of the layers property at index 1 as a keyframe
    # for properties that have no index, the 2nd argument can be omitted
    sphere.keyframe_insert("layers", 1)

layer_set(1, False)
layer_set(10, True)
layer_set(20, False)

The above snippet will make the cube visible on the second layer for frames 10-19. You can use keyframe_insert for every property of the StructRNA this method is called on. I suspect the same is true for the driver_add-method, although I have not experimented with that method.
