Personally, I am not using xf86-input-void, because I am using
standard system mouse with synaptics touchpad, so I don't need
'void' input device.

If you'll look at 
  http://gitweb.freedesktop.org/?p=xorg/xserver.git;a=blob;h=dbe158efc6e365cd5bd064d848df3a4f0c0d35f4;hb=43d9edd31e31b33b9da4a50d8ab05004881c8d5a;f=hw/xfree86/common/xf86Config.c#l1611
you will see that server tries to add the mouse driver if there is
no drivers of type 'mouse' or 'void'.  The hack with adding the "dummy"
input device with type "void" disables generation of default mouse
driver.  This was the true hack and it was a bit beautified in
http://gitweb.freedesktop.org/?p=xorg/xserver.git;a=commit;h=ba9f5138fc32a7a7b97bcf941bc92751b7c6c2c0
now there is a boolean option "AllowEmptyInput" that inhibits creation
of core mouse and keyboard in any case.

Xorg server 1.4 already has "AllowEmptyInput", so Giulio and others
who want to run only Synaptics driver, can add the string
-----
Option "AllowEmptyInput"

to their "ServerFlags" section and see no automagically added devices.
