I gave up and restored a backup onto a host without the EFI boot
partition and tweaked it to use the old-style grub invocation.   The
machines seem to fail back to 'legacy' mode when there is no EFI/fat
partition to boot from.  This gives a layout where rear and clonezilla
'just work'  and I'll know how to fix it if anything breaks.   Maybe
I'll try again when rear supports UEFI (in the works) and I can look
at their shell scripts to figure it out.
