Pretty much correct. To enable Ivy PM, you also must have an sysdef that is appropriate for Ivy CPU, which depends on what specific CPU you have.
I forgot to mention that I used Chameleon Wizard to create the smbios.plist with this definition: MacBook Pro 9.2. It has i7 3520M Ivy Bridge CPU, HD4000 and GT650M just like me (I'm not quite sure whether I have a 640M or 650M but it's useless anyway in OS X).
Then you should verify by looking at ioreg to see if x86platformplugin is loading under CPU nodes. And run pstate checker in DPCIManager to verify pstates are being reached.
There is no x86platformplugin loaded. When I search it nothing shows up. Do I have to enable P/C States? they're currently both off. And I found a NullCPUPowerManagement kext in Extra/Extensions. Could this (also) be a problem?
