I think DSP vs CPU for better battery life is mostly a myth. Both are processors, and both need power. The advantage of using the DSP is for better performance without putting heavy load on the CPU.

DSP should be able to do the same work with fewer cycles and therefore use less power, however as the ARM cpufreq frequency is pegged when the DSP is running, it may be less efficient to use the DSP when there's nothing else to be done on the ARM. Anyone happen to know the power consumption of the ARM1136 with very low load but a fixed cpufreq?

Nokia should know the answer, I wonder if it's old enough for them to release a hint to us?
