You don't appear to have passed a dom0 kernel to Xen. e.g. it is not listed
as a MODULE[N].

See 
http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions#Booting_Xen
 which describes how to setup the DTB to reference the kernel boot module
etc.

It would also be useful if you would post your complete boot script.

Also, I'm CCing the original contributors of the Lager support, since we
don't have much knowledge of this specific platform or where to get kernels
from etc.
