Yeah, that seems to work. It boots now and it says:

[    0.000000] efi: No EFI runtime due to 32/64-bit mismatch with kernel

Do you think we should mirror that behavoir early too, so that people
don't get any ideas?

Or should we limit that only to the RDSP address computation and
anything else where kernel and EFI bitness mismatch should be disabled?

Thanks Ard!
