Could you point me to some more info about this (I couldn't find any bug reports)?

If I remember right, if you load p4-clockmod and try to set ondemand as governor, cpufreq will refuse the to change the governor. On i686, linux even refuses to build the performance governor as a module, even if it is not the default.

Doesn't the kernel config discourage the use of p4-clockmod? " This driver should be only used in exceptional circumstances when very low power is needed because it causes severe slowdowns and noticeable latencies. Normally Speedstep should be used instead. " -- -- Rogutės Sparnuotos
