Hah, I bought a new G965 system, but could not source one with DVI anywhere, so I bought an ADD2 card with DVI.
It doesn't even want to think about working. No bios, no boot, no X. The modesetting branch does recognize the existence of the ADD2 card and produces no display at all. The documentation for configuring the driver is full of undescribed terms (grovelling in the source explains some (LFP/DFP) but not all). I don't know what a pipe is, really and how it might be used or not used in my system.
As someone who can download code from version control and read source to an extent, this configuration for (6 month old?) hardware still doesn't work in Linux. I feel the announcement was premature.

LCA: Updates on the X Window System

After loading the Windows driver from Intel for the GMA x3000, suddenly DVI out on the pegasus ADD2 card worked.
The modelines I had been using for the device under VGA for a matrox card were still for some reason required (Under X.Org 7.1.x) and the presence of the 1400x1050 line for some reason caused the output to be blurry. Leaving only the 1600x1200 line in the xorg.conf, for my 1600x1200 Dell 2001FP allowed the display to come up nicely.
Remaining problems with the i810 driver:
- Changing resolutions with CTRL-ALT-+ and - results in a virtual desktop where not all regions can be reached, and the mouse display does not match the mouse click events. xrandr does not have this problem. The support for virtual desktops with scrolling appears broken.
- With the Mesa 6.5.1 based dri, opengl texturing has issues, and some kind of assertion against malformed pipeline instructions typically crashes openGL programs on context teardown.
- With Mesa 6.5.2 and 6.5.1 glx, many opengl applications crash the X server or corrupt the display. Sometimes the 1.7.2 version of the i810 driver cannot reinitialize the display, reporting lockups during attempts, forcing a reboot.
