Someone did suggest that you can force the original autodetection to run again by deleting one of the files and rebooting: you may like to search for that.
'mkxf86config' is the command to make a new xf86config-4 file but it will only make one if there is no existing file so you have to delete /etc/X11/XF86config-4 first.

If masticate has done a knoppix type hd install *most* of the hardware autodetection will be taken care of but not x-config because the XF86Config-4 does not get deleted after each boot like it does on the CD.
