We have 4 ports on i386. 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.
