Good, then the size of the EDID block makes sense. Not sure if there is something else which is non-standard with the EDID information. I guess it has to be something, since the 1600x1200 mode is not listed in Xorg.0.log after the EDID for HDMI1.

Since it does not make a difference for the resolution and we want to keep the test case as simple as possible, we would like to have only the HDMI/DVI connected when troubleshooting this. Also please move away /etc/X11/xorg.conf so that we have a standard configuration (it should not make any difference for the behaviour). Could you provide `xrandr --verbose`, `dmesg` and Xorg.0.log for that case?

We would also like the same logs for the UMS case (i.e. nomodeset boot option). Even though it does not make any difference in behaviour, there may be differences in the logs.

If you have access to a computer (with intel graphics chipset) with DVI output it would also be a useful data point to know what happens if you connect the monitor to that. You don't need to install ubuntu on that computer, a LiveCD/LiveUSB test would do. Still, the logs for that case would be interesting (can be copied off the LiveCD session).
