The nVidia Quadro NVS 450 has two GPUs on it, type G98 The card has four ports allowing for four displays nouveau appears to: a. Not support the G98 chip b. Not support multiple GPUs c. Not support more than two displays Making this card work could be a good idea! https://bugs.launchpad.net/ubuntu/+source/linux/+bug/889538
NV98 is definitely supported now, as are multi-GPU setups. Take a look at http://nouveau.freedesktop.org/wiki/MultiMonitorDesktop/ for how to get that going. Make sure you're running the latest nouveau software, as there have been some fixes specifically related to the NVS 450.
