Subject: High pitch noise when ACPI processor module is loaded.

Hi,

Linux:
When I do not load the ACPI processor module, there is no high pitch 
noise.  When I load the ACPI processor module (so I can utilize Turbo 
Boost), Linux makes the system emit a high pitch noise.

Windows:
The same system, running Windows 7 does not emit any noise.

Is there something wrong with the ACPI processor module or its 
implementation on i5/i7 CPUs?

Justin.
