Kernel 2.6.35 misalignment

We seem to have a situation with 2.6.35.  This is on a DH57DD, i5-661, Intel 2.12.0, server 1.8.2, Mesa 7.8.2, the only difference between working and not working being vs. 2.6.35, so I am assuming it is in DRI somewhere.

I have a dual monitor, as follows.

Screen 0: minimum 320 x 200, current 3600 x 1080, maximum 8192 x 8192
HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 477mm x 268mm
HDMI2 connected 1680x1050+1920+0 (normal left inverted right x axis y axis) 433mm x 271mm

On 2.6.35 about a quarter inch of the left side of what is on HDMI1 is displayed at the very right of HDMI2 (it is also in the correct position on HDMI1).

Also, the HDMI2 display is displaced about an inch and a half to the left, with black between that and the bogus left side of HDMI1.  The leftmost part of HDMI2 is nowhere on either monitor.  If I move a window on HDMI1 to the right until it starts to appear on HDMI2, that inch and a half is missing by the time it just starts to appear on HDMI2.

I took a screenshot to show you, with the window that is taking the screenshot in the position overlapping the boundary between monitors, and it is correct.  On the actual display, the leftmost visible thing is half of the US flag at the bottom and the OOo Calc icon at the top.  I've posted the screenshot at

For now I suppose the best thing is for other people to be alert for this and see if others can reproduce it.
