* Enabling Magic SysRq Key on boot before INIT

Hello,

I would like to enable the Magic SysRq key immediately when the linux
kernel starts to boot, not when INIT begins. So, I am familiar with the
sysctl command and /etc/sysctl.conf - but I'd like to modify these types
of kernel variables earlier in the boot process. I thought that I could,
perhaps, pass an argument to my "kernel" line in my bootloader (grub)
configuration, but I have not been able to figure that out.

Is this possible?

Thanks,

I thought that Eric was asking if it was possible to alter sysctls
by adding boot command line arguments.. if he was, then the answer
is no, it's not (in general).
