I think that KDM chooses screen 0 as default. I have a nvidia card and
running twinview and this is the related settings in my xorg.conf:

Section "ServerLayout"
        Identifier      "DefaultLayout"
        screen  0       "ScreenDualHead0" 0 0
        Inputdevice     "MSComfortCurveKeybord2000"     "CoreKeyboard"
        Inputdevice     "MSWirelessLaserMouse5000"      "CorePointer"
        Inputdevice     "AverMediaRemote"                       "SendCoreEvents"

Section "Screen"
        Identifier      "ScreenDualHead0"
        Device          "NvidiaGeForce8500GT"
        Monitor         "SamsungSyncMaster957mb"
        Defaultdepth    24
        Option          "NoLogo"        "True"
        Option          "TwinView"      "1"
        Option          "TwinViewXineramaInfoOrder"     "CRT-0"
        Option          "metamodes"     "CRT-0: 1280x1024_85 +1152+0,
CRT-1: 1152x864_75 @1152x1024 +0+0; CRT-0: 1152x864 +1152+0, CRT-1:
1152x864_75 +0+0; CRT-0: 1024x768 +1024+0, CRT-1: 1024x768 +0+0;
CRT-0: 800x600 +800+0, CRT-1: 800x600; CRT-0: 800x600 +0+0, CRT-1:
NULL; CRT-0: 640x480 +640+0, CRT-1: 640x480; CRT-0: 640x480 +0+0,
        #Option         "TwinViewOrientation"   "CRT-1 LeftOf CRT-0" #
If no offset is specified in metamodes
        #Option         "ConnectedMonitor"      "CRT-0, CRT-1" # If
one monitor is of when booting or on a switch
        #Option         "ConnectedMonitor"      "CRT-0, TV"

        SubSection "Display"
                Depth   24
