After manually installing and configuring cpufrequency everything is fine. As a lot of users are working on laptops it will be really great if cpufrequency could be enabled by default. Thank you.

Thanks Ben for pointing this out. Did not know it's enabled by default
now. I just checked and can confirm that the ondemand governor and
acpi-cpufreq driver are set even withouth "cpufrequtils". So this is
probably much less needed than for squeeze.

Tested on a Thinkpad X200.
