@Litold: please check your CPU governor - maybe your machine purposely sets the lowest frequency when CPU unloaded... You may also recheck when the CPU is under high load.
Another thing I've remembered to mention - it doesn't matter if I boot a 32- or 64-bit system, with both scaling works fine with older kernels up to 2.6.32-24, and doesn't work at all with any newer kernel.
