There were many questions regarding the oldschool xorg/x11 setup without hald/dbus and with old usefull terminate method by ctrl-alt-backspace, here is a short howto how to achieve this.
1. Install FreeBSD along with x11/xorg or add it by package.
1.1. Enable and start moused(8) daemon if you already do not have it running.
2. Generate new config.
3. Move config to its proper place.
4. Add needed options to config in sections ServerFlags and InputDevice.
5. Basic client configuration.
6. Start x11/xorg.
Example full xorg.conf config:
For comparision, for OpenBSD its like that:
1. Install OpenBSD along with xenocara/x11.
2. Basic client configuration.
3. Start x11/xorg.

If you would like to disable CAPS LOCK key, then you should make the folllowing change in the xorg.conf file:
If you would like to also set other then default keyboard layout, then add this to xorg.conf file:
1. Install FreeBSD along with x11/xorg or add it by package.
root # pkg_add -r xorg
1.1. Enable and start moused(8) daemon if you already do not have it running.
root # echo moused_enable=\"YES\" >> /etc/rc.conf
root # /etc/rc.d/moused start
root # /etc/rc.d/moused start
2. Generate new config.
root # X -configure
3. Move config to its proper place.
root # mv /root/xorg.conf.new /usr/local/etc/X11/xorg.conf
4. Add needed options to config in sections ServerFlags and InputDevice.
root # vi /usr/local/etc/X11/xorg.conf
The following options are needed to have working x11 without hald/dbus:
... and following for "three kings" or CTRL-ALT-BACKSPACE terminate keyboard shrtcut:
Code:
Section "ServerFlags"
(...)
Option "DontZap" "off"
Option "AllowEmptyInput" "off"
Option "AutoAddDevices" "off"
EndSection
Section "InputDevice"
(...)
Option "XkbOptions" "terminate:ctrl_alt_bksp"

5. Basic client configuration.

6. Start x11/xorg.
user % xinit -- -dpi 75
