Depends on the hardware. It *does* stress the on-board power regulator a
damn great deal if you do it on a power-hungry desktop CPU.
The acoustic noise I mentioned are caused by interference of the electric
noise it generates on insuficiently protected audio circuitry. Yes, I have
seen this first hand on some ThinkPads. My T43 doesn't appreciate ondemand
much, for example...
It is probably not good for the battery of a laptop either. Steady-state
drain is always better AFAIK, and ondemand will make the drain that much
