Slater, I used my Leopard 10.5.7 install to install SL to a different partition, then added my Kext, boot loader, and dsdt.aml files and I was up and running in 32bit mode. Have to repair permissions and boot with -F and -V the first time. see if that helps ya.

Jaraeez, I will try and make a walkthrough when I have some time, maybe over the weekend..
