Hey anybody want to look into an interesting possibility?
Now this is a long shot but... hear me out...
OK I have had 2 T61P's in my hands that had this graphics issue.
Both of them have a little rubbery pad under the keyboard that was off center. Here is a picture showing what I mean:
Ignore the red circle, look where the pink arrow is pointing:

OK see how the purple rubbery pad is the same shape as the metal object it sits on, but it's not centered? It's shifted to the right.
Well, both the "bad" laptops I have seen had this pad shifted just like that. However, when I got a NEW T61P that appears to NOT have this problem, I took off the keyboard and guess what? The pad is not shifted, it is perfectly centered!
So, if anyone is not afraid to take off the keyboard and check this (it's pretty easy, if you have accessed your RAM before, to take the keyboard off only requires unscrewing 1 extra screw on the bottom, the one with the keyboard picture by it, near the middle of the bottom).
I would be very curious to hear from those of you who have this issue, whether your pad is offset or not, and those of you who don't have this problem as well.
Those who had the problem fixed at the depot, you don't count, because the depot guys might have straightened the pad, which means nothing.
The only reason I'm curious about this is because I just wonder if there was some issue with the assembly line that has been since corrected, or something like that, just wondering if there is any correlation between the shifted pad and the graphics issues. If there is a correlation, it might provide an easy way to identify which laptops have the problem and which don't.
EDIT: Removing the palm rest and / or keyboard does NOT void your warranty. I am 100% sure of that.
