I think this is the problem:  /netbsd-XEN should be the first module
to be loaded. xen.gz will use the first module as dom0 kernel.
I'm not sure entropy-file will work with a Xen dom0 kernel (this is
new, I've not had time to play with it yet).

Maybe try to put the rndseed entry after the load entry ?
