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.
