Actually, as pointed out later by Robert, modular Xorg won't help
as it doens't support this graphic device either.
On linux Xorg is using the modesetting driver so I tried this:

Section "Device"
        Identifier "Nvidia T400"
	Driver "modesetting"
	BusID  "PCI:1:0:0"
	Option      "Monitor-DP1" "Monitor0"
	Option      "Monitor-DP2" "Monitor1"
EndSection

And this works; even with a  dual-HEAD output.

glamor is not working for some reason:
[   323.179] (II) Loading sub module "glamoregl"
[   323.179] (II) LoadModule: "glamoregl"
[   323.180] (II) Loading /usr/X11R7/lib/modules/libglamoregl.so
[   323.181] (II) Module glamoregl: vendor="X.Org Foundation"
[   323.181]    compiled for 1.21.1.9, module version = 1.0.1
[   323.181]    ABI class: X.Org ANSI C Emulation, version 0.4
[   323.259] (EE) modeset(0): eglInitialize() failed
[   323.259] (II) modeset(0): glamor initialization failed

but that's not so important for me; glxgears with default options is giving
more than 250FPS which should be good enough for my use case (my current
workstation gives 60FPS :).
mplayer is slow though; that could be annoying as more and more documentation
come as video. Will try modular Xorg and see if it's better.
