Use ACPI tables to decode valid frequency/voltage pairs

configname: CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI

Linux Kernel Configuration
└─>CPU Frequency scaling
└─>Use ACPI tables to decode valid frequency/voltage pairs
In linux kernel since version 2.6.12  
Use primarily the information provided in the BIOS ACPI tables
to determine valid CPU frequency and voltage pairings. It is
required for the driver to work on non-Banias CPUs.

If in doubt, say Y.
