Default LINUX mprime does not switch speedstep off

This may be by design, but the latest 64-bit version of mprime doesn't run with a nice level high enough to trigger the flip of speedstep from low to full.

For example, my X3360 speedsteps down to 6x333 when idle and 8.5x333 which under load - except when mprime is loading it! It doesn't matter which of the three torture tests I run, all four cores get loaded @ 100 % but at 70 % power (6x333). I have to manually tweak the nice level from -19 to 0 to invoke speedstep applying full power to the machine.

Just wanted to report this behavior even if it's known and by design :)
