Yes, so what?
The problem with your patch is that now to enable kdump, I have to know
that there's a second command line option and if my firmware is "broken"
or not. The former is already a problem (how do I even know such a
thing exists?) but the latter is almost impossible to solve from user
point of view. And if I have a "broken" firmware, kdump won't work no
matter what options I pass.
I really don't see what's practical about that.
