I'm wondering how come the i386-qemu port works if none of its
initialization code takes into account gate A20. Does this
mean it's supposed to be already disabled in initial CPU state,
and only enabled by BIOS?
Or maybe the code only works by chance and would break unexpectedly
in specific situations?
