Xen users - Oct 2012 - kdump on Xen 4.1, ubuntu 12.04 and kernel 3.2.0

I seem to be struggling with setting up kdump to debug Xen/dom0 freeze.
According to http://xenbits.xen.org/docs/unstable/misc/kexec_and_kdump.txt the
"crashkernel=" parameter must be passed to the Xen hypervisor. When it
is
passed to Xen I dont see "Crash Kernel" under System RAM in
/proc/iomem
inside dom0. I am missing something obvious here. Could someone please
explain why the crash kernel region is not listed in /proc/iomem in dom0 ?
