On balance it would indeed be a fair amount of complexity for an edge
case. One other (hopefully more useful thought) - it should be easy to
build another copy of boot, set to load at just under 4m and install
as /usr/mdec/boot4m?

Thanks again for the fix (and for remaining polite while someone from
