ideally, the presence of that flag in the firmware table will clear/set more global settings,
for example, having that flag should cause the 8042 input code to not probe for the 8042.

for interrupts, there really ought to be a "apic first/only" mode, which is then used on
all modern systems (not just hw reduced).
