I think item 2 above is wrong (AutoAddDevices false).
xorg.conf should have something like this:
Section "InputDevice"
    Identifier  "Mouse"
    Driver      "mouse"
    Option      "Protocol"      "auto"
    Option      "Device"        "/dev/input/mouse0"
EndSection
Section "InputDevice"
    Identifier     "Keyboard0"
    Driver         "kbd"
    Option         "XkbLayout" "us"
    Option         "XkbModel" "pc105"
EndSection
