Here is the story.  When I filed this bug we did I did a fair bit of
testing with the upstream with no success.  When I tried the same with
Windows XP, I got the same issue. When I told upstream, they decided to
close it since it is obviously it is a hardware issue that even XP can't
fix.

After much digging and trying I discovered the following:

- The problem stems from a weird firmware in these screens that makes think they are in TV mode and not in PC Monitor mode hence the shift.
- I think the newest release of Xorg has a bunch of EDID enhancement that might be worth testing. I will be happy to test if there is a PPA for the new Xorg stuff. I have an ATI (GM780) desktop machine.
- I tried Lucid with my thinkpad (GM4500HD) and ATI and have the same problem so this is an Xorg and not an intel driver issue.

Rrecommended action:

- File a bug with the Xorg team (not the intel driver team) 
- Review this: http://forums.extremeoverclocking.com/showthread.php?t=310242 . They try to get the EDID and force X to use it. I tried it but it doesn't work on both intel and ATI.
- I am more than willing to help figure this bug out. Let me know how I can be of assistance.
