These keys are mapped correctly in the kernel, but a limitation on the number of distinct keycodes that X can handle prevents these from being communicated to the X server.
To work around this, you can use setkeycodes to map the key to a keycode below 256 that you aren't using, then use xmodmap to map this keycode to the desired keysyms.
