Was this documented somewhere or did you look at the ctrlaltdel example 
and modify it? I think the difference is crtl-alt-del is a hardware 
interrupt and ctrl-alt-f is not, so the kernel doesn't intercept it, and 
init never sees it. (Years ago I thought I could do something like this 
and make a hot key that started Doom for me)

You might want to look at /usr/src/linux/Documentation/sysrq.txt, but that 
probably isn't a drop-in solution for what you want.

Another idea would be to write a daemon that checks the state of the 
connections, and if it finds something wrong (for some definition of 
wrong) it configures the system into a failsafe mode.
