I don't know any firm reasons why that wouldn't work, but I can just
suggest some tweaks that work for me. Do things change if you run
"startx -- -nolisten tcp ..." instead of explicitly calling xinit? And
do things change if you add "exec" in front of the mwm line? I would put
Option "CoreKeyboard" in the keyboard section. I also have:

InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"

in my ServerLayout section. Lastly, /dev/sysmouse looks new to me. If
it's a valid device that's fine, but I find out what the device nodes
are from looking at /proc/bus/input/devices.

If "modprobe evdev" works, you have the module, otherwise you don't.
With evdev, the devices all look like "/dev/input/event*" and you don't
need sections for them. You just need udev to be running. That is,
"udev" should show up in ps -e output.
