using my DTS cpufreq series (which I am about to post to linux-omap):

and a test script:

I See (3.9-rc3):

bogomips@ boot:
BogoMIPS : 395.67
Boot scaling frequency =600000
TESTING for 1 seconds at 300000
current scaling frequency(for 300000) =300000
bogomips@ frequency 300000:
BogoMIPS : 197.83
TESTING for 1 seconds at 600000
current scaling frequency(for 600000) =600000
bogomips@ frequency 600000:
BogoMIPS : 395.67
TESTING for 1 seconds at 800000
current scaling frequency(for 800000) =800000
bogomips@ frequency 800000:
BogoMIPS : 527.56
