Rationale:

I want to be able to use SYSRQ to reboot, crash or partially diagnose machines that become unresponsive for one reason or another. These machines, typically, are blades or rack mounted machines that do not have a PS/2 connection for a keyboard and the old method of wheeling round a "crash trolley" that has a monitor and a keyboard on it no longer works: USB keyboards rarely, if ever, work because by the time the machine is responding only to a ping, udev is incapable of setting up a new keyboard.g/majordomo-info.html

This module is starting to look kind of useful. Maybe its time for
a resubmission for review and possibly merging once these patches
are included.

If we were to merge it, it would also be good to get some feedback
from the crypto guys about whether the chosen authentication scheme
meets its claims.
