To my knowledge no Linux distro packages install media supporting 32-bit firmware and 64-bit kernel+CPU, but it's definitely possible to built a 32-bit GRUB EFI binary and have it load and execute a 64-bit kernel on a 64-bit CPU. I've done it on such a Mac. And there are a number of tablets built this way also (unfortunately).

Intel only contributed the code for that a year ago, so while we now know it can be done, there's no particular reason to believe that it's easy to get working properly. The messy mix of EFI 1.x and UEFI 2.x that Apple uses could make things even trickier.
