I'm still curious to why I couldn't install SL with bootpack and EDP. I was able to install Lion with no problem using bootpack and EDP. The best I could get with SL was 10.6.3, with a kext package I found on another site and all update attempts failed.
I've got two hard drives, one with Lion, fully updated and SL. In my opinion Lion doesn't run nearly as well as SL on my D630
