output of dmesg command

This concerns a Quadro NVS 450 with two/dual GPU, driver NV50.

Everything is recognized, dual head on the primary GPU works fine, even
unplugging and then plugging in the monitors (DP-1, DP-2, DP-3 and DP-4), but
after a day and a halve I cannot find any more information online and have to
get to work (using the proprietary drivers for now).

Using debian with:
linux-image-3.0.0-1-amd64 3.0.0-3
xorg 7.6+8
libdrm-nouveau1a 2.4.26-1
xserver-xorg-video-nouveau 1:0.0.16+git20110411+8378443-1+b1
