Except that neither "qemu-system-x86_64 -bios vmlinux" nor
qemu-system-x86_64 -kernel vmlinux" will load an ELF kernel on x86-64.
The code to do this _exists_ within qemu, it's just not hooked up
consistently on all targets. We have a universal cross-platform image
format, and we have support in qemu for loading that format, and for
some reason it's only enabled on certain targets. I've never understood
why...
