well the keyboard and the monitor may still be "far" from the 'puter...
and the 'puter may be in public use... so being able to block magic
sysreq on a system without rebooting to a kernel without it would be cool...
(block as in still have it behind some "top secret" run-time
configurable thing... as in root-accessable /proc config thingy or something)
[and for those few who think about control-alt-del: init can secure that one easily]
