Here it is some dmesg output with cpufreq.debug=2

Here starts the userspace program (cpufreqd):

speedstep-ich: transiting from 731500 to 731500 kHz
from now on the frequency stays on 731500 kHz..
I've tried to read informations from the sys interface:
cat scaling_available_frequencies : 1130500 731500
cat scaling_min_freq : 731500
cat scaling_max_freq : 731500
trying to change frequency through scaling_setspeed does nothing.
I've also noticed these errors during ACPI startup
acpiphp: ACPI Hot Plug PCI Controller Driver version: 0.5
decode_hpp: Could not get hotplug parameters. Use defaults
acpiphp: Slot [1] registered
acpiphp_ibm: ibm_find_acpi_device: Failed to get device
