opensource nvidia, xinerama

Tue Feb 20 19:10:28 UTC 2007

Hi, 
I have a nvidia 7600 card. It has one VGA _and_ on DVI output.
I also have one DVI to VGA (harware) converter.
Two screens, strictly the same.
I intend to run Edgy Eft (Kubuntu).
Is there any possibility that the Xinerama mode will work?
I mean: sharing a laaaaaaarge desktop on  the two screens
(not cloning/mirroring) _with_ the opensource drivers. I dont 
want to use proprietary drivers.
Is it possible?
If some has nearly the same hardware, I would ask for their xorg.conf, please.
Thank you!
PS: I found some howtos, but thei're ATI/proprietary driver
