vbios XFX Nvidia 7300 GS 256MB

I already talked in IRC #nouveau before reporting this bug.

Card:
http://images10.newegg.com/NeweggImage/ProductImageCompressAll300/14-150-410-02.jpg

Problem: Card connected to an 24" 1920x1200 monitor via DVI. Everything is
working fine with windows and DVI at full resolution.
When booting any Linux live, i get a black screen directly when KMS starts.
BIOS post and VESA works fine with DVI.
To get a picture with nouveau, i had to connect the same monitor via VGA cable
to the nvidia card. I get then an 1024x768 resolution.

After boot with VGA i remove the VGA cable and connect DVI to get some logfiles
for debugging.
first:
for p in /sys/class/drm/*/status; do con=${p%/status}; echo -n
"${con#*/card?-}: "; cat $p; done

reports in VGA-mode:
DVI-I-1: disconnected
TV-1: connected
TV-2: disconnected

reports in DVI-mode (no working screen):
DVI-I-1: disconnected
TV-1: disconnected
TV-2: disconnected

The xorg log:

the dmesg:

The vbios from /sys/kernel/debug/dri/0/ :

(also attached to this bug as attachment)

The IRC log with some additional information that are maybe usefull:
https://pastebin.mozilla.org/8825683

Would be nice to get able to use this computer with nouveau and DVI with normal
resolution.
