Better to do this for i386 too, no?
"On systems that support IA-32e mode, the extended feature enable
register (IA32_EFER) is available. This model-specific register controls
activation of IA-32e mode and other IA-32e mode operations."

Can it be useful for i386 too?

That's on Intel. AMDs had EFER before 64-bit support (for syscall support, and nx), IIRC.
