Yep, I could reproduce it, thanks for reporting.

Almost, you need acpi-cpufreq (CONFIG_X86_ACPI_CPUFREQ) also as module
so that mperf.ko gets compiled as a module too since its being shared
between the two. Otherwise it is statically linked into whichever of the
two (apci-cpufreq or powernow-k8) are built-in.

Fix follows.
