I didn't review the whole patch, but it seems to be fine.
The tests I did on hardware went all like they should.

I've tested this patch on M57SLI.
The SSDT.dsl tables from a plain cb-v2 rev. 4367 and the same rev. with this

PowerNow remains working, like it should, and there are no differences after 
patching cb in the SSDT.dsl tables.
