A proper implementation of grub_cpu_idle should work fine on all of them. When I say "proper" I mean that 'hlt' instruction should be usable without doing strange gimmicks. Your patch simply works around the fact that 'hlt' is broken on 32-bit by going back to i8086 mode in order to use it. -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us.
