Isn't something like this generally sufficient for a shell script?

lspci -n | grep -q "5853:0001"
if [ $? -eq 0 ]; then
	# HVM domain
elif [ -d /proc/xen ]; then
	if grep -q "control_d" /proc/xen/capabilities; then
		# DOM0
	else
		# DOMU
	fi
else
	# Native
fi

It seems fairly reliable on ia64 for Xen 3.x.  Thanks,
