Because it requires to build 32-bit file. As I said before this patch will work even the OS can't load 32-bit executables at all. I'm not sure about compiling it as a 64-bit file because it generates another code; moreover x86_64 accepts regparam=6. Perhaps it would detect bug... but who knows?

I can't understand what you mean. If it is support for ELF64 multiboot then it already presents in GRUB (see multiboot.c file).
If it is ELF64 multiboot & switching to 64-bit mode then it is MISTAKE because it requires enabling paging and it's not clear at all.
If it is 64-bit version of GRUB utilities then my patch already provides it
