Synopsis: [i386] [request] Intel Core i7 and Nehalem-EP new features not supported

State-Changed-From-To: feedback->closed

State-Changed-When: Fri Sep 24 07:35:27 UTC 2010
State-Changed-Why: 
The issue as described in this PR is not present in stable/8.
ACPI in stable/7 is not going to be updated.
In stable/8 C3 is reported but is never used in default
configuration, because processor never sleeps long enough
to C3 state with that long enter/exit delay.
The reporter is tuning his system for optimal performance.
