--- Comment #11 from Dushan Tcholich <dusanc at gmail.com> ---
I have same problem using Gentoo, but I had working setup with 1.12, but got
the exact same problems when upgraded to 1.13
Everything is same with kernels from 2.6.39 to 3.6.6
Cards are Radeon HD3450 and HD5430

Only the first server starts, and 2nd one fails with:
(EE) RADEON(0): [drm] failed to set drm interface version.
(EE) RADEON(0): Kernel modesetting setup failed

I'm using GDM and custom.conf is:

name=Standard server 0
command=/usr/bin/X1 -config xorg.conf.1 -nolisten tcp -layout seat1 -novtswitch
-isolateDevice PCI:3:0:0 -sharevts -xinerama -keeptty

name=Standard server 1
command=/usr/bin/X0 -config xorg.conf.0 -nolisten tcp -layout seat0 -novtswitch
-isolateDevice PCI:1:0:0 -xinerama -keeptty

xorg.conf.1 has:

Section "ServerFlags"
    Option         "DefaultServerLayout" "seat1"
    Option         "AllowMouseOpenFail"  "true"
    Option         "AutoAddDevices"      "false"
    Option      "AutoEnableDevices"     "false"
    Option         "DontVTSwitch" "yes"
    Option         "DontZap" "yes"

Section "Device"
    Identifier     "Device1"
    BoardName      "ATI Radeon3450"
    Driver         "radeon"
    BusID          "PCI:3:0:0"
    Option         "AccelMethod" "EXA"
        Option      "ProbeAllGpus" "false"
    Option      "Monitor-DVI-1" "Monitor1"
