I just upgraded my system to Linux Mint 14 (Linux 3.5.0), and Zaphode Mode
stopped working in the new system.

This is my simplistic xorg.conf that I used to achieve Zaphod Mode (maybe a
little different, because the original was lost in the upgrade and I based
it on an old backup):

Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0 "Screen0"
        Screen      1 "Screen1" RightOf "Screen0"
EndSection

Section "Monitor"
        Identifier   "Dvi0"
EndSection

Section "Monitor"
        Identifier   "Dvi1"
EndSection

Section "Device"
        Identifier  "Card0"
        Driver      "radeon"
        VendorName  "ATI Technologies Inc"
        BoardName   "RV770 [Radeon HD 4870]"
        Option      "ZaphodHeads" "DVI-0"       # <str>
        BusID       "PCI:2:0:0"
        Screen 0
EndSection

Section "Device"
        Identifier  "Card1"
        Driver      "radeon"
        VendorName  "ATI Technologies Inc"
        BoardName   "RV770 [Radeon HD 4870]"
        Option      "ZaphodHeads" "DVI-1"  # <str>
        BusID       "PCI:2:0:0"
        Screen      1
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Dvi0"
EndSection

Section "Screen"
        Identifier "Screen1"
        Device     "Card1"
        Monitor    "Dvi1"
EndSection

But when I launch XOrg, I get these lines on the log (the most relevant
line marked):

...
[   811.224] (++) using VT number 7

[   811.232] (II) [KMS] Kernel modesetting enabled.
[   811.232] Requested Entity already in use!
[   811.232] (II) [KMS] Kernel modesetting enabled.
[   811.232] (EE) Screen 1 deleted because of no matching config section.
<-- (Only mention to "Screen1")
[   811.232] (II) UnloadModule: "radeon"
[   811.232] (II) RADEON(0): Creating default Display subsection in Screen
section
        "Screen0" for depth/fbbpp 24/32
...

and so on with "Screen0" configuration, with no other mention of "Screen1".
The X session starts with a single screen. What is wrong with this config
file? Why Xorg can't create the other screen?
