This patch is in reference to bug#:51741. (https://bugzilla.kernel.org/show_bug.cgi?id=51741) powernow-k8 falls back to acpi-cpufreq if CPU is not supported. However, it states that acpi-cpufreq has taken over even if acpi-cpufreq is not compiled in. This patch rewords the warning message to clarify that the CPU is unsupported and prints a warning message when there is no acpi-cpufreq present.
