For Ctrl-Break and Ctrl-C, install a signal handler for the signal SIGINT 
and make it just return.  Check out the docs for the `signal' library 
function in libc.inf reference.

To disable Ctrl-Alt-Del, you will have to install a hardware keyboard 
interrupt handler, or hack the crt0.s (which already installs such a 
handler) and make it watch for this combination and not pass it down the 
line.
