Preventing Xorg from creating input-devices

[Tyler Aviss]

I'm having major issues with Xorg trying to be a bit "too helpful" lately.
I have an LCD with a touchscreen, and have defined the appropriate
input section in xorg.conf and added it to my server layout

Section "InputDevice"
    Identifier "lilliput touchscreen"
    Driver "evtouch"
    Option "Device" "/dev/input/lilliput"
#    Option "Device" "/dev/input/event6"
    Option "DeviceName" "touchscreen" #udev-created symlink to
/dev/input/event6, prevents devices from changing ID's
#    Option "MinX" "65"
#    Option "MaxX" "1978"
#    Option "MinY" "20"
#    Option "MaxY" "2000"
    Option "SwapX" "1"
    Option "SwapY" "1"
Option "MinX"   "65"
Option "MaxX"   "1978"
Option "MinY"   "1673"
Option "MaxY"   "2000"
    Option "ReportingMode" "Raw"
#    Option "Emulate3Buttons"
#    Option "Emulate3Timeout" "50"
#    Option        "MoveLimit" "10"
    Option "SendCoreEvents" "On"
    Option "CorePointer"
    Option "Calibrate" "0"
EndSection


However, xorg creates it's own device which takes over the event
interface before mine instantiates, and that devices has completely
WRONG minX, maxY etc params.


from Xorg.0.log

Anyone know a way to tell xorg to NOT do this?
