You don't need the rebel efi disk for anything beside install and 1st boot. My process is as follows:

1. Boot with "Free Trial" of Rebel EFI and select snow leopard DVD.
2. Install OS
3. Boot with Rebl EFI and select the hard drive I installed onto.
4. Download the chameleon installer package and install chameleon. http://chameleon.osx86.hu/file_downl...2-r640.pkg.zip
5. Download the latest Chameleon and copy just the boot file to the root of your drive

6. Reboot into your new awesome Snow Leopard
