No, i used speedstep-centrino with 2.6.16.

I tried acpi-cpufreq but it didnt create /sys/devices/system/cpu/cpu0/cpufreq
directory and there is no warning/error exists on dmesg.
zangetsu cpu0 # lsmod | grep acpi
acpi_cpufreq 7620 0
freq_table 4640 1 acpi_cpufreq
processor 30920 2 acpi_cpufreq,thermal
zangetsu cpu0 # lsmod | grep ondemand
cpufreq_ondemand 6604 0
zangetsu cpu0 # cd /sys/devices/system/cpu/cpu0/
zangetsu cpu0 # ls
crash_notes topology
zangetsu cpu0 # rmmod cpufreq_ondemand
zangetsu cpu0 # rmmod acpi_cpufreq
zangetsu cpu0 # modprobe speedstep-centrino
zangetsu cpu0 # lsmod | grep speed
speedstep_centrino 8768 0
freq_table 4640 1 speedstep_centrino
processor 30920 2 speedstep_centrino,thermal
zangetsu cpu0 # lsmod | grep ondemand
cpufreq_ondemand 6604 0
zangetsu cpu0 # cd /sys/devices/system/cpu/cpu0/
zangetsu cpu0 # ls
cpufreq crash_notes topology
zangetsu cpu0 # cd cpufreq/
zangetsu cpufreq # echo "ondemand" > scaling_governor
zangetsu cpufreq # cat scaling_governor
ondemand
zangetsu cpufreq # cat scaling_available_frequencies
1733000 1333000 1067000 800000
zangetsu cpufreq # cat scaling_cur_freq
1733000
But frequency never changes and stays at 1.73ghz
zangetsu cpufreq # echo "powersave" > scaling_governor
zangetsu cpufreq # cat scaling_cur_freq
800000
zangetsu cpufreq # echo "performance" > scaling_governor
zangetsu cpufreq # cat scaling_cur_freq
1733000
Cheers
