EFI 32 bits nightly build (broken?)

Hi all, i tried to boot lakka with a hp x2 pc10 detachable. it seems that it needs a 32bits efi (otoh the 64bits android-x86 booted ok). i got the 32bit efi nightly and if i enter the bios it show a 64efi img inside boot directory (from the x86 .gz img) maybe the nightly script is not putting the right boot img inside the nightly image?

best regards, edited i noticed that openelec doesnt support uefi, maybe would worth upstream?
