Some unordered/random/quick thoughts...
1/ There seems to be a problem with the driver. As you are using Squeeze
with nvidia cards, the driver to load should be either "nouveau" or "nv"
but no "fbdev". My will guess is that the VGA cards are too new for
Squeeze's xserver Xorg packages, maybe you need to update these or that
simply KMS is having some sort of problem to be loaded.
2/ You can also try the closed source nvidia package which usually works
very well. More info about your options can be found here:
http://wiki.debian.org/NvidiaGraphicsDrivers/
3/ For setting up Xorg with dual cards (that is, two physical devices
plugged) and also configuring an extended desktop, you may also need to
manually adjust your xorg.conf file settings. Some hints here:
