IMHO, it is an debug feature, so it should be *diabled by default*.
After all you don't want random Joe to come to your machine and
play random stuff with it.
However, since you want to have it enable as early as possible during
kernel booting, as I see the soluion is to add it as
command line option to pass to kernel.
Just my 2 bits aligend to 16bits boundary.
