An EFI 64-bit kernel can only be loaded by a 64-bit EFI bootloader. With Linux 
I think it doesn't matter because I think even with the EFI stub you get a 
hybrid kernel that can be booted by a regular bootloader, but things like the 
EFI framebuffer driver and efivars will not work unless you boot in EFI mode.

You can chainload an efi bootloader with grub1 but I think that only emulates 
EFI, so these things may still not work. And I don't think that's officially 
supported anymore because there's grub2 for that purpose.
