Hi Bryce!

1- Carl first noticed it while certifying some systems, he stumbled upon a particular resolution that triggers the problem. Since we hadn't run the full, exhaustive set of tests on Natty, this was the first time we noticed it. I then went back to Maverick to confirm whether it'd happened there as well.

2- No, it's only on the 1360x768 resolution, and only on those two machines; to begin with, very few systems support that particular resolution, and none of the others exhibit the problem.

3- I connected an external monitor and switched to the problem resolution on the built-in display, it's still crooked/slanted. The external monitor shows no change. I then used xrandr to cycle through all available resolutions on the external display; none of them exhibit the problem on that display (though it's independent from the built-in one). The external display doesn't support 1360x768 so I was unable to test that :(

4- I'm attaching xrandr and Xorg.log from Maverick, booted with a LiveCD.

5- I tried the indicated kernel, the slanting/crooking problem still persists :(
