Only if you prove that the current implementation does not work, I will 
consider it.

I have already investigated how other systems deal with Gate A20. For example, 
Linux does not do such a thing, but nobody has reported that it does not 
work.

Did you really read the code? GRUB tries to enable Gate A20 until it is 
enabled. What is wrong with this?

GRUB does not use such addresses.
