In the Etherboot
There is an option
You need to enable it to use Etherboot boot elf with X86-64 kernel.

Stefan already gave the practical explanation. The small bit beyond
that is the x86_64 kernel does not even have a valid 64bit entry point.
The code is actually present in the 32bit etherboot to cope
with an 64bit in for x86_64. But except for test programs
I have not been able to find any native ones.
