Those "HF" releases wouldn't exist if not for PackageMaker, an application included in the Developer Tools package.
But PackageMaker is only one the many apps that come with Developer Tools - there's that very helpful IORegistry app for checking out your hardware as you tinker with DSDT, and Xcode of course, etc. But then there's also CHUD.
I get Kernel Panics more often with VoodooHDA reported as misbehaving which didn't happen when Developer Tools still weren't installed in my system.
Enter CHUD remover:
I normally just search for it from Spotlight, so I wouldn't know the exact path to the remover.
Apparently, CHUD kexts (they get installed in /S/L/E btw) do not play well with VoodooHDA.kext.
