install the latest chameleon so far it's 1518 with chameleon wizard to your installer disk and it's modules folder. make sure graphics enabler is selected in org.chameleon.Boot.plist and you set your native res... make sure you have an extra folder on the installer drive with your dsdt.aml, org.chamelon.boot.plist, and proper smbios.plist for a macbook3,1. if you install and run edp on the external installer drive with edptool.command and build for your model it should supply all this, except the dsdt wich is intended for 1280x 800 screen... so replace it with your higher res. dsdt. keep the build simple no sleep/null no battery as you only need to install the os.
