You will get the message.  Specifically, sys/kern/link_elf.c will emit this 
message (because it can't handle an amd64 .ko) even though 
sys/kern/link_elf_obj.c will work ok.  Basically, if link_elf.c tries the 
module first, you get this message.  Since kernel object files are linked in 
alphabetical order, link_elf.c ends up always probing potential kernel 
modules first.
