Trying to reduce X.org

[Jonas MG]

The keyboard is compiled of dynamic form with the section InputDevice of 
xorg.conf:

 Section "InputDevice"
       Identifier  "Keyboard0"
       Driver      "kbd"
 
       Option    "XkbRules"  "xorg"
       Option    "XkbModel"  "pc105"
       Option    "XkbLayout" "en_US"
 EndSection

In order to do this, it needs the directory '/usr/X11R6/lib/X11/xkb' that 
occupies 2,9 M. But it would be possible to be compiled the keyboards that to 
us needed and to be reduced the size.

For this I used:

xkbcomp -xkm -m en_US /etc/X11/xkb/keymap/xfree86

And I obtain the keyboard 'en_US' with a size of 9K

Can I load this keyboard from xorg.conf? How?
