I've been running a similar system at my place for years..
I never have to restart Xorg, all screens are available at once.

They are all different X screens (not xinerama, mirror or anything
like that). One xorg.conf

All of different resolutions.

It's quite simple to set up really...

You have 3 monitors sections, 3 devices sections, and 3 screen sections.
Each device section contains an Option "UseDisplayDevice" "xxx" and Screen x
Where xxx is the name of the video interface (one of DFP-0, DFP-1,
CRT-0 etc..) and x is the number of the screen it points to (0,1 or 2)

In order to have this setup and beeing seen as this by the nvidia
drivers even when one of the screen was off. you use the CustomEDID
function

So this is my first Device section:
Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"
        VendorName  "NVIDIA Corporation"
        BoardName   "GeForce 8600 GT"
        Option      "CustomEDID" "DFP-0:/etc/X11/viewsonic-edid.bin; DFP-1:/etc/
X11/panasonic-edid.bin"
        Option      "ConnectedMonitor" "DFP-0,DFP-1,CRT-0"
        Option      "UseDisplayDevice" "DFP-1"
        Option      "UseEvents" "True"
        BusID       "PCI:1:0:0"
EndSection
