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?
