I should have said, that output was from

menu=Boot Xen:consdev com0,57600;load /netbsd-XEN3_DOM0 console=com0;multiboot /xen-debug.gz dom0_mem=1024M console=com1 com1=57600,8n1,0x3f8

so exactly like an older message, without the rndseed bit, which apparently
caused the "not an ELF binary" error.

Thanks for the suggestion.
