I've used SpeedStepper to patch AppleIntelCPUPowerManagement.kext for Mac OS Snow Leopard 10.6.8 and all versions of Lion.
SpeedStepper for Lion 10.7.3, applied to "AppleIntelCPUPowerManagement.kext, version 167.3.0" works with Lion 10.7.4
Before rebooting after updating Lion 10.7.3 to 10.7.4, I deleted the Lion 10.7.4 version of AppleIntelCPUPowerManagement.kext, and used an app to install the previous patched version for Lion 10.7.3. You can do this manually or use terminal, the system is still in root mode.

My system Specs . . .
Motherboard: Zotac H67-ITX-C-E
CPU: Intel Core i7-2600K
GPU: Sapphire ATI Radeon 5770 (model 100283-3L)
DSDT: Edits for HDMI audio only required, all else is vanilla
WiFi: May require swapping card for an Atheros or Broadcom, or use RaLink Driver for Mac OS.
All works, no issues.
