Does the pandora have the "ondemand" cpufreq scaling? On AMD I think it's called Cool'n'quiet and what it does is changing the cpu frequiency depending on cpu load. ie on my desktop if cpu load is at 100%, the freq is 2400Mhz, but when idle it's at 1000Mhz, with a few other frequencies between. Well, it's a very common thing on laptops since a long time ago, and it's becoming popular on desktop cpus since some time..it's nothing new
