ACPIDUMP for bios F.17

Bios F.17 is better than F.11.
When you boot with speedtep-centrino, frequency change beetween 1GHz and
1,33GHz but (from HP forum) if you execute
echo 1833000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo 1833000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
frequency as it should beetween 1GHz and 1,83GHz.
So it seems last bios is nearly working except for fan problem. But why
speedstep-centrino is limiting the speed to 1,33GHz?

Philippe.
