Windows doesn't do because there is no 32/64 mixed windows and EFI on
the planet. Since the silicon is actually 64 bit, I failed to see a
reason to refuse the user install 64bit linux on it. So we encountered a
case windows didn't.

So, you didn't mention BOOT_BIOS, if you don't want to add BOOT_BIOS,
and you also don't like DMI entires, how do you want to deal with the
machines requiring BOOT_BIOS to reboot their machine?
