Yes, but you must plan for it in advance and the task should not contain normal shaders or texturing.
First thing that was done with SPUs was trimming of vertex data to make it fit RSX better. (culling invisible polygons, animations and so on.)
Then SPUs were used for post processing like DoF and motion blur, this gets a nice load off from RSX.
Now many games use deferred rendering/lighting and the actual light accumlation pass and such things. (Uncharted2 and Battlefield3.)
