Well, I think that interface should export the BIOS memmap as provided.
Since E820 does provide 64 bit addresses, that should get exported.

It should even possible to kexec a PAE kernel from a non PAE kernel ...
I didn't test, but it could work. But only if the E820 map is correctly
written in the zero page, which is only the case if we get it correctly.
