Thanks. I've now tested this on a 64-bit EFI system myself:

x86_64 kernel build:
- Boots successfully
- x86_efi_facilities = 0x3f
- efifb works
- efivars can be loaded and creates /sys/firmware/efi/vars

i386 kernel build:
- Boots as far as an initramfs shell, but the machine doesn't have an
i386 installation to continue with
- x86_efi_facilities = 0x21
- efifb works
- efivars can be loaded but does nothing

All of which I think is correct.
