(credit: Randolph brought it up first)

Look at arch/parisc/kernel/setup.c:setup_cmdline().
We can add pretty much anything we need here.

It just occurred to me that the source media (ie network, disk)
needs to be identified as well.
Is the vmlinux/System.map required to be on the root file system?
Would it be reasonble if savecrash told the user that /boot/vmlinux
wasn't the matching kernel and where to put the right vmlinux/System.map?

Allowing users to drop the right kernel in place *after* the
crash dump was recovered seems reasonable thing to do.
Someone might want to move the crash dump to a bigger/faster
system to do the actual analysis.
