Forgot to mention something..
The personalities blocked by kext blacklist: { "com.apple.driver.AppleIntelMeromProfile", 0 },
{ "com.apple.driver.AppleIntelNehalemProfile", 0 },
{ "com.apple.driver.AppleIntelPenrynProfile", 0 },
{ "com.apple.driver.AppleIntelYonahProfile", 0 },
{ "com.apple.driver.AppleIntelCPUPowerManagement", 0 },
the cpu family Profile ones are blocked because they cause a huge hang at boot (right before getting to login window) when booting with "64 bit mode" enabled or k64. Obviously, they don't need to be blocked for Core cpus.
Don't know if these are relevant for power management?!
