Intersting stuff. I'll try those two, but I'm very hesitant to peg the CPU since that seems like a horrible waste of power. Changing the governor to performance does seem like a sweet trick. Maybe I can write a little app that can apply either performance or batterylife with a max speed limit based on the locking status.
Changing the governor to performance does peg the CPU. (With the exception that if a DSP task is present, it falls back to 330 MHz to boost DSP throughput.)
