We've already got Alt+SysRq+k, which Wikipedia's description says will
"Kill all processes on the current virtual console (Can be used to
kill X and svgalib programs, see below) This was originally designed
to imitate a Secure Access Key".  

Of course since sysrq-magic has been disabled by default for a while
now, this will still require that an echo of "1" to
/proc/sys/kernel/sysrq be done at boot.
