Each user's device driver knows how to put up the SAK login screen on it's head.
The SAK is only going to kill thing assoicated with that head. This works
because each card's driver is required to support the system console at the
kernel level.
SAK will always be available from any head. We will need a kernel option to
control whether the rest of the system console (pintk, kdbg, etc) is available
from any head or just the boot device.
Ctrl-Alt-Del has to be the SAK key. It will reset the graphics and start a new
login process.
SysReq will get you the system console. System console will show printk, kdbg,
OOPs, etc.
Both of these keys will be active even if X is running. You can toggle between
system console and user console. But system console is not a shell, no one is
logged in on it. It can only be used to run dedicated things like kdbg.
