With the standard kernel, the boot loader pass informations about the boot
device to the kernel using a NetBSD-specific protocol. With Xen we have to use
the multiboot protocol (which comes from the linux world), and there's no
provision here to pass boot device informations. In this case we have to go
the linux way, and use the root= parameter. When such parameter is absent,
the kernel tries to use the first probed disk as root device.
