  comment "CPUFreq processor drivers"

-config X86_POWERNOW_K8
+config  X86_POWERNOW_K8
         tristate "AMD Opteron/Athlon64 PowerNow!"
         select CPU_FREQ_TABLE
         help
           This adds the CPUFreq driver for mobile AMD Opteron/Athlon64 
processors.
+         An acpi interface is available if acpi support has been selected.
+         This is required for multi-socket and other systems but not 
necessarily required for UP single socket systems.

           For details, take a look at <file:Documentation/cpu-freq/>.

           If in doubt, say N.

  config X86_POWERNOW_K8_ACPI
-       bool
-       depends on X86_POWERNOW_K8 && ACPI_PROCESSOR
-       depends on !(X86_POWERNOW_K8 = y && ACPI_PROCESSOR = m)
+       bool "ACPI Support"
+       select ACPI_PROCESSOR
+       depends on X86_POWERNOW_K8
+       help
+           This provides access to the acpi tables for full p-state 
functionality. This driver is also required
+           for cpufreq to work with multi-socket and other smp systems.
+
+           It is safe to say Y here.
         default y

  config X86_SPEEDSTEP_CENTRINO
