[Bug 81682] [snb] Frequent framerate drops (cpufreq?)

--- Comment #32 from Greg Sutcliffe <bugsfreedesktop at emeraldreverie.org> ---
Sorry for the delay, life got in the way.

I've had a look through the kernel config I have available to me. I seem to
have this:

Power management and ACPI options
| CPU Frequency scaling
| | x86 CPU frequency scaling drivers
| | | [*] Intel P state control (X86_INTEL_PSTATE [=y])
| | | <M> ACPI Processor P-States driver (X86_ACPI_CPUFREQ [=m])

I don't see scpi_cpufreq loaded in lsmod, so as far as I can tell, that means
I'm defaulting to the pstate driver here? If so, I'll recompile the kernel
without it and let acpi_cpufreq pick it up and retest.
