Xorg.0.log from openSUSE 13.1 milestone 4

Initial summary:
using DVI to VGA adapter for CRT and specifying supported "PreferredMode" >EDID
preferred mode, screen output is compressed into small fraction of top scan
lines

To reproduce:
1-connect DVI-I out from NVidia PCI express card (G84 here with only dual DVI
out; DVI-I-1 connected) to CRT supporting up to 2048x1536 but with 1600x1200
preferred (NEC FE2111SB here) via PCI to VGA adapter
2-set 'Option "PreferredMode" "1920x1440"' in 'Section "Monitor"' in
/etc/X11/xorg.conf*
3-start X server

Actual results:
1-entirety of video output displays into top scan lines, approximately 4mm or
less in height
2-usable desktop only for those who can use it without seeing video output

Expected results:
1-normal display output
2-normally usable desktop
3-"normal" even if fallback to EDID preferred 1600x1200 is necessary to do so
due to gfx hardware device limitation

Notes:
1-Does not happen with pure VGA connection with any gfxchip or driver.
2-Does not happen with same 3 DVI-to-VGA adapters connected to Radeon (rv380;
S-video, VGA-0 & DVI-0 available; DVI-0 connected) DVI output.
3-Problem dates back at least to openSUSE 11.4 with
xorg-x11-driver-video-nouveau-0.0.16_20110115_b795ca6-3.1.i586 installed and
server 1.9.3.
4-Problem remains at least through server 1.14.2 and
xorg-x11-driver-video-nouveau-1.0.9-1.3 on openSUSE 13.1M4, and server 1.14.1
on Fedora 19 with xorg-x11-drv-nouveau-1.0.7-1.fc19.
5-Happens with or without specific port specified via Option in 'Section
"Device"'.
6-Happens on both 32 and 64 bit x86 installations.
