I've had the following problem:
I have kernel 184.108.40.206.
I compile cpu frequency control into it, with ACPI and APM.
When enabling ACPI (upon boot), cpufreq works fine.
When I enable APM, I don't get /proc/cpufreq or /sys/.../cpufreq - in other words,
Any idea why that could be? I'd appreciate some help, after spending ages trying to figure it out...
