You can adjust the nice value via the Prioryty setting in prime.txt. Priority 1 corresponds to nice 19, priority 10 is 0.

The point of SeedStep is to save power, and the only time SpeedStep saves power is when a process uses 100% CPU. Power consumption while idling is far below power consumption while working at any frequency, and does not depend on CPU frequency as most of the CPU is switched off. It is best to leave the frequenzy at max to make short bursts of activity complete as fast as possible, staying idle most of the time. Speedstep s only useful when a backgrond task like mprime is using 100% CPU all the time. In that case you save some power by lowering the CPU frequency, but get less work done as well.
