I have tested this on 2.6.32.3 to 2.6.32.5 and with 2.6.32-trunk-amd64 from
debian/testing. Since cpufreqd 2.3.3-4:
1. current policy: frequency should be within 3.17 GHz and 3.17 GHz. instead
of current policy: frequency should be within 2 GHz and 3.17 GHz., while
available frequency steps: 3.17 GHz, 2.67 GHz, 2.33 GHz, 2.00 GHz and hardware
limits: 2.00 GHz - 3.17 GHz rendering it unusable.
2. cpufreq-aperf shows weird frequencies.
3. The hardware is capable of stepping those frequencies, which can be proved
on running cpufeq-info shortly after a fresh boot with result:
cpufreq stats: 3.17 GHz:99,84%, 2.67 GHz:0,00%, 2.33 GHz:0,00%, 2.00 GHz:0,16%
4. Changing the governer does not solve it, It looks like it is not bound to a
particular governer.
Here is what i did.

CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 2.00 GHz - 3.17 GHz
available frequency steps: 3.17 GHz, 2.67 GHz, 2.33 GHz, 2.00 GHz
available cpufreq governors: conservative, userspace, powersave, ondemand,

current policy: frequency should be within 3.17 GHz and 3.17 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 3.17 GHz (asserted by call to hardware).
