Button Driver

The kernel module as well the test application is done. 

But how to make this device communicate to Xserver and therefore to Xclient.

For example, the touch panel (char driver / node ttyS1 / MAJOR 4) communicates via xorg's xf86-input-dmc driver.
Similarly, how do I make the push buttons (char driver / node button / MAJOR 211) communicate to the Xserver ?

Am I missing something or losing track, please let me know.

google for kbdd or kbde.  Both will do what you want; kbdd is a user 
space implementation and kbde is a kernel space implemenation.
