I have no idea what happened... maybe the upgrade from 3.2.28 to 3.2.29 broke something.

Have a look at line 823 in /etc/rc.d/rc.modules and set the CPUFREQ option to on. i had to do that on my desktop machine to activate frequency scaling.
I also don't see a reason why this is off by default.
I did the windows thing (format and reinstall)... and now i have it working..

analyzing CPU 0:
driver: acpi-cpufreq
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: 800 MHz - 1.60 GHz
available frequency steps: 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
available cpufreq governors: ondemand, userspace
current policy: frequency should be within 800 MHz and 1.60 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 800 MHz.
