X searches through a list of standard locations for the config file (which
indeed are different for version 4).  From the man page for XF86Config-4:

       When the X server is started by the "root" user, the config file
       search locations are as follows:
 
           <cmdline>
           /etc/X11/<cmdline>
           /usr/X11R6/etc/X11/<cmdline>
           $XF86CONFIG
           /etc/X11/$XF86CONFIG
           /usr/X11R6/etc/X11/$XF86CONFIG
           $HOME/XF86Config
           /etc/X11/XF86Config-4
           /etc/X11/XF86Config
           /etc/XF86Config
           /usr/X11R6/etc/X11/XF86Config.<hostname>
           /usr/X11R6/etc/X11/XF86Config-4
           /usr/X11R6/etc/X11/XF86Config
           /usr/X11R6/lib/X11/XF86Config.<hostname>
           /usr/X11R6/lib/X11/XF86Config-4
           /usr/X11R6/lib/X11/XF86Config
 
The one with the -4 on the end appears first, so yes, for X 4 that's the one
to edit if both exist.  Another thing to note is that if /root/XF86Config
exists, it will be used instead!
