That's fine. In the ACPI code, we currently have no support for managing 
thermal conditions through anything other than the processor. Once that 
changes, it's easy to fix this up so it doesn't interfere with thermal 
zones that are handled by throttling other devices.

Menlow has a more complex thermal model than machines we've seen up to 
now, but I was under the impression that this was to be handled by the 
new generic thermal class rather than the existing ACPI code. I don't 
see this patch as being in conflict with supporting that.
