Personally I use the SMBIOSPatcher, ACPIPatcher, Resolution, GUI, USB, etc... modules.
Only the essentials.
Hello world isn't required ofcourse
You can enable P and C states with a boot flag (isn't stored in my brain so I'll have to look it up )
ACPIMini is only DSDT patching (not needed if you use ACPIPatcher).
Helloworld is a little example of how a module can be written (not needed).
KextPatcher is used to patch modules like AppleIntelGMA950 etc....
Resolution auto detects the best boot resolution for Intel, NVidia and ATI cards.
Symbols is the collection of all modules (which is required if you use modules).
