see the FREQ lines?
exemple: 850:60,600
850= CPU freq
60= CPU voltage lvl
600 = dsp freq
But dsp freq @ 600 seems to be the max. you may be able to go further, but it is at your own risks!

why not just simply load dsp profile ?
root
kernel-config load dsp
simple. whenever you will restart you N900 default profile will be loaded and you have to load dsp profile again.
