that would be DontZap which is a boolean (man xorg.conf)
add this section to the bottom of your /etc/X11/xorg.conf file providing
it doesnt already contain a serverflags section which it wont by default

Section "Serverflags"

Option "DontZap"      "yes"


keep in mind though its there for a reason, but if you find yourself
ctrl-alt-xx regularly and cant help hitting the backspace i can imagine
it would be annoying.
