I agree that's a long term solution, meanwhile can we just hope
that not too much boot memory is reserved and not free
that memory so it at least boots for more people?

Maybe add a printk of 'X amount of boot memory will not freed',
so at least people can quantify and judge for themselves whether
it's worth disabling kernel efi support or not.
