I guess I misunderstood the original issue. You have available_frequencies showing all the values and after you load ondemand, frequency remains at the highest, even though CPUs are idle. Is this correct?
And everything above used to work fine with 2.6.16?
Can you configure with CPU_FREQ_DEBUG and do "echo 5 > /sys/module/cpufreq/parameter/debug" before switching the governor to ondemand and see whether you see any messages in dmesg?
Thanks,
Venki
