I'm not a kernel tuning expert ;-)) However: a) my kernel config is: CONFIG_X86_64=y CONFIG_64BIT=y CONFIG_GENERIC_CPU=y CONFIG_X86_CPUID=y # CPU Frequency scaling CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_TABLE=y # CONFIG_CPU_FREQ_DEBUG is not set CONFIG_CPU_FREQ_STAT=y # CONFIG_CPU_FREQ_STAT_DETAILS is not set CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y # CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=y CONFIG_CPU_FREQ_GOV_USERSPACE=y # CONFIG_CPU_FREQ_GOV_ONDEMAND is not set CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y # CPUFreq processor drivers CONFIG_X86_ACPI_CPUFREQ=y # CONFIG_X86_ACPI_CPUFREQ_PROC_INTF is not set # CONFIG_CPU5_WDT is not set b) I do not use cpudyn, although recommended by the Gentoo Linux AMD64 FAQ.
