What is weird?  The fact that if linux.ko is not loaded, the kernel
does not know what to do with an unknown ELF binary type? :)

What I find weird is the fact that as soon as linux.ko is loaded,
the kernel "learns" to treat type 0 binaries as type 3; but this is
probably because Daniel Eischen has at some earlier time set
the kern.fallback_elf_brand sysctl to 3.

G'luck,
Peter
