Phillip, please could you provide sources/links showing that "64 bit UEFI firmware generally will only load a 64 bit boot loader, by firmware limitation" ?
or if this is just personal experience, please could you indicate which firmware/computers you have seen with this limitation ?

Title:
grub-efi 32 bits fails on 64bits computer
Status in “grub2” package in Ubuntu:
Invalid
Bug description:
On a 64bits EFI computer (with GPT disk) with pre-installed 64bits
Windows7. Laptop ASUS N76VZ-V2G-T1002V.
1) Installed Ubuntu 12.04 32bits in dual-boot, then installed grub-
efi. Result: http://paste.ubuntu.com/1069331 (see the 3 efi files on
sda1). At reboot, GRUB menu does not appear, even when setting the EFI
BIOS on /efi/ubuntu/boot.efi , or /efi/ubuntu/grubia32.efi .
2) Removed the Ubuntu32bits partitions, and replaced it by Ubuntu
64bits. Result: http://paste.ubuntu.com/1072125 (see the new
/efi/ubuntu/grubx64.efi file). At reboot, the GRUB menu appears and
allows to boot Ubuntu.
