I just did a succesful installation on a medion akoya S2217, which also has a 32 bit UEFI
the only hitch I encountered was that, while booting the livecd correctly, it installed the 64 efi boot bin. I had
to manually install the grub-efi-ia32 packages after installation.
(just for completeness: I copied over the livecd bootia32.efi to the boot disk to be able to boot the system into a grub command line, from where I could boot the installed system, then I could install the
32 bit grub packages)
