This isn’t quite true. See 3a3fcc75f92ab0d71ba (" pc: acpi: force FADT rev1 for 
440fx based machine types”) where the fadt table size for i440fx is no longer 
*fadt but offsetof(typeof(*fadt), reset_register). The above commit simply 
makes sure we do not populate reset_register etc for i440fx since its not used 
anyway.
