In case there's anyone still reading this thread who isn't a ranting conspiracy theorist with communication issues...
I've had some success with marrying up msycamore's excellent PCM rip of the 70mm mix with a 720p version of the Blu-ray video.
The result, as it stands, is a Blu-ray/AVCHD format disc which fits on a single layer DVD. No menus or other fancy stuff, just the movie with superb audio.
If you'd like to see/hear this, let me know - it's certainly a good stop-gap until the 5.1 version is succesfully ripped, and I should think a few of us are planning on re-watching the original movie ahead of the release of Prometheus NEXT WEEK!
