But raid is missing here. Does "ext2 pc gpt raid _chain" work? (at least,
to get to the rescue console)

There are two separate problems here. I can't comment on the LBA addressing
issue, but if we can isolate the partmap detection one, then at least we can
"fix" [1] this (which is what affects the majority of users).
[1] With a kludge that loads "pc gpt" when partmap cannot be detected. Not sure
if this is suitable for official grub, but at least we would enable it in
Debian.
