Application to Dynamically Adjust Processor Speed

Here's the developers website:

nueDynamicClock

This should work on the Saga, no? I found a spec sheet that lists the processor as "384 MHz MSM7500", which would fit the paramenters mentioned in the pocketnow article. At first, I thought this might be used to overclock the CPU, but that doesn't seem to be the case. However, it should, in theory, increase the battery life. Anyone feel like trying this one out?
