ACPI Support found in arch/x86/kernel/cpu/cpufreq/Kconfig

The configuration item CONFIG_X86_POWERNOW_K8_ACPI:

• prompt: ACPI Support
• type: bool
• depends on: ( CONFIG_X86_32 ) && ( CONFIG_ACPI && CONFIG_X86_POWERNOW_K8 && CONFIG_ACPI_PROCESSOR ) && (!( CONFIG_X86_POWERNOW_K8 = CONFIG_y && CONFIG_ACPI_PROCESSOR = CONFIG_m ))
• defined in arch/x86/kernel/cpu/cpufreq/Kconfig
• found in Linux kernels: 2.6.24–2.6.29

Help text

This provides access to the K8s Processor Performance States via ACPI. This driver is probably required for CPUFreq to work with multi-socket and SMP systems. It is not required on at least some single-socket yet multi-core systems, even if SMP is enabled.

It is safe to say Y here.
