Some tests in DOS show that A20 is disabled on boot. BIOS A20 functions
(enable/disable/read status) seem to work correctly. And debugger shows that
BIOS uses port 92h...

So probably GRUB enables A20 using BIOS. Linux would do the same if A20 was
disabled. And BIOS itself is buggy, INT 15h uses 92h but resume requires KBC. 

Is there anything that we can do except adding some DMI-based quirk?
