FWIW, I have a local change to boot to allow autoloading of modules to
be disabled. 

My reading of the Xen sources when I first looked at the bootloader
was that it would look at each module to see which one contained the
Xen signature. I don't think this is still the case, it seems to just
assume the first one in the list is the Dom0.
