The code is at:
http://anonscm.debian.org/cgit/d-i/debian-installer.git/tree/build/config/x86.cfg#n335

and has:

		xorriso -as mkisofs -r -J -b isolinux.bin -c boot.cat \
			-no-emul-boot -boot-load-size 4 -boot-info-table \
			-eltorito-alt-boot \
			--efi-boot boot/grub/efi.img -no-emul-boot \
			-o $(TEMP_MINIISO) $(TEMP_CD_TREE); \

I guess -e is short for --efi-boot?

I don't suppose I can tempt you into sending a patch against the above
git repo, can I? ;-)
