I think the 1.2v problem may be a bit of a red herring. I bought cheapo 1.2v RAM for troubleshooting purposes, and still got the 07 post code.
It may be an issue for those attempting to overclock RAM, but I do not believe it's behind the 07 post codes.
Edit: To be clear, I don't think you are saying the two are related, but at one time I thought they were.
