Thinking about this split, there might be a way to simply it even more.

/sbin/kexec can load the "Xen" crash kernel itself by issuing hypercalls
using /dev/xen/privcmd. This would remove the need for the dom0 kernel
to distinguish between loading a crash kernel for itself and loading a
kernel for Xen.

Or is this just a silly idea complicating the matter?
