Default not able to drive ibm t221 3840x2400 screen with 81.78 (was ok with 76.76)

have tried to upgrade from 76.76 to 81.78 a box which drive an ibm t221 3840*2400 screen.
Whith 76.76, i had found the modeline to achieve that :

http://www.nvnews.net/vbulletin/show...highlight=t221

But with 81.78, theses modelines no more works : i have in the Xorg.0.log :
Not using default mode "2624x2400" (bad mode clock/interlace/doublescan)

with 76.76 i had theses :
(**) NVIDIA(0): Mode "2624x2400": 211.2 MHz, 73.7 kHz, 59.8 Hz (I)

I have tried to use the get-edid function of the nvidia-settings control panel, it gives me others modelines :

# Monitor preferred modeline (48.0 Hz vsync, 117.8 kHz hsync, ratio 1.09) (bad ratio)
ModeLine "2624x2400" 328 2624 2672 2704 2784 2400 2402 2412 2455 -hsync +vsync

# Monitor preferred modeline (48.0 Hz vsync, 117.8 kHz hsync, ratio 0.51) (bad ratio)
ModeLine "1216x2400" 164 1216 1264 1296 1392 2400 2402 2412 2455 -hsync +vsync

but with 81.78 theses modeline does not works neither, i have the same bad mode clock/interlace/doublescan problem ...

does anyone knows how to drive the t221 with 81.78 ?, i need to upgrade because we use stencil with frame buffer object, and 76.76 is not able to do that.

Thanks
Alexandre
