I don't understand this bit about the 32/64 bit efi rom in the 8800. The previous generation mac pro is a 64 bit machine as well, what's the need for the 32 bit?
No, because they don't say either way. I don't recall Apple ever saying that it was (not) an EFI problem, but if you can find a release about it, then I'd concede the point.
Not that there's much to concede, I just don't recall them leaning either way.
