Hey Bettarg, welcome dude. Here is what I did.

First. Go and download PCWIZ's DSDT Patcher GUI and then the Disabler.kext HERE

Second. Run the DSDT Patcher GUI- Choose Darwin / Mac OS X (duh). Then check the 3 check boxes to the right. Select your hard drive. Click run DSDT Patcher button.
let it do it's thang.

Third. Unzip (if you haven't already) the Disabler.kext to your desktop. Use Kext Helper (probably found in the iDeneb folder in your Applications folder if you installed it when you installed iDeneb) Drag and drop the kext into the program. Type in your password and click "Easy Install"

Go to Software Update... Choose only the 10.5.6 update for now, grab some dill pickle sunflower seeds, sit back and relax.
