No, such an option shouldn't exist at all. You should be passing
information *in* *a* *different* *manner* to the kdump kernel - not with
a kernel command line option.

I get the feeling I'm starting to sound like a broken record on this
mail thread... :-(

One other thing we could probably try to do is use boot_params which
is, IIUC, passed to the second kernel. So we can add another bit to
boot_params.hdr.loadflags or so and use that. Or something similar.

Not particularly crazy about it but it is still much better than a
command line param...
