This seems to happeon on my Thinkpad T60 (Core 2 Duo 2 Ghz) too:
sudo cpufreq-info
cpufrequtils 002: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to [EMAIL PROTECTED], please.
analyzing CPU 0:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 1000 MHz - 2.00 GHz
available frequency steps: 2.00 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: userspace, ondemand, powersave, conservative,
performance
current policy: frequency should be within 1000 MHz and 1000 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1000 MHz (asserted by call to hardware).
analyzing CPU 1:
driver: acpi-cpufreq
CPUs which need to switch frequency at the same time: 0 1
hardware limits: 1000 MHz - 2.00 GHz
available frequency steps: 2.00 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz
available cpufreq governors: userspace, ondemand, powersave, conservative,
performance
current policy: frequency should be within 1000 MHz and 1000 MHz.
The governor "performance" may decide which speed to use
within this range.
current CPU frequency is 1000 MHz (asserted by call to hardware).
So while Linux knows there are several modes, it only allows cpufreq to use the
slowest of them...
