I got only one CPU, but two CPU cores - by CPU you meant "CPU core", right?

arch/x86/kernel/include/asm/cpufeatures.h

I'll try that with a vanilla kernel to see if I run into other problems with
that. (That will remove the capability system-wide, not only for the cpufreq
subsystem, right?)

If it helps: I installed Windows XP on another partition on my affected laptop,
frequency scaling works just fine there...
