Use /sys/devices/system/cpu/cpu0/scaling_cur_freq or even cpuinfo_cur_freq for that.[*] So p4-clockmod-throttling does work on your p4 prescott.

[*] Available in 2.6.7, hopefully, if Linus merges the latest cpufreq-bk tree from Dave. It'll be in the next -mm release, though. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
