Is PowerNow loading? I have:
powernow-k8: Found 1 AMD Athlon 64 / Opteron processors (version 1.60.0) powernow-k8: 0 : fid 0x8 (1600 MHz), vid 0x4 (1450 mV) powernow-k8: 1 : fid 0x0 (800 MHz), vid 0x16 (1000 mV)

Try:
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 is not set CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y 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 is not set
CONFIG_X86_POWERNOW_K8=y CONFIG_X86_POWERNOW_K8_ACPI=y # CONFIG_X86_SPEEDSTEP_CENTRINO is not set CONFIG_X86_ACPI_CPUFREQ=y
And if it doesn't work try enabling CONFIG_CPU_FREQ_DEBUG
