This is what the cpu_info kstat is showing on Kuriakose's laptop (thanks Vinay):
supported_frequencies_Hz 800000000:1200000000:1600000000:2000000000:2400000000:2401000000 I'm wondering what the essential difference is between the 2400 state and the 2401 state (besides 1 MHz, and i'm guessing that's not even the difference)... Thanks, -Eric
