I ran across this other day, you guys who are working & developing solution should check out URL.
FYI - On my Mac Pro using Areca 18809ix-8 Controller with EFI firmware. I was able to get LION, Windows 8 Preview UEFI, & Ubuntu 11.10 UEFI install with out any headaches. Only thing i had to do was convert W8.iso using ocdimg cmd. & install Ubuntu Desktop x64 version using UEFI on Fat32. Plus Bootcamp Drivers are working in W8 Preview.
