No

As outlined in the OP.

I used my own-generated xen.efi, since Opensuse's support didn't work.

I had NO startup.nsh.  It was not necessary.

With my .efi, and Opensuse 13.2, boot simply worked -- exactly as expected.

I upgraded to Opensuse Leap, and now use the Opensuse-generated efi

The upgrade changed grub -- 20_linux was modified to "handled" efi.

The upgrade broke grub, requiring the patch, above.
