Since i'm not one of the mods/owners of infinitemac, i don't know. You can try the method i just posted, since i, as you, don't have a ssse3-enabled Bulldozer CPU. It worked for me, maybe it works for you. Installing OsX in general (and Lion particularly) on any kind of AMD machine is never a piece of cake and. There's no AMD-supportive Uni/Multibeast-like method and probably there never will.
