I thought there was also a suggestion that we could fail gracefully in
the EFI stub if we detected an unsupported page size?

Yup. There are other things we could/should test, too.

I believe Jeremy had a patch, but due to churn in that area it didn't
get picked up.

I will clean-up and re-post that patch in the future too. It was fairly trivial so if someone feels the need for immediately...

IMHO, The main sticking point initially was that the correct place for the check was a moving target. That problem has been fixed, so it should be easy to move it.
