i have a patch (that takes a command line argument to override this)
that more-or-less does that, by default it will frob all VIA devices
if no IO-APIC or is present or you can pass an argument to always do
everything or do nothing

i was hoping we could figure out something smarter than just looking
to see if an IO-APIC was found though, maybe someting like checking if
ACPI actually did something sane, but i know zilch about the ACPI side
of things

i can refresh that against, -git and -mm if people want it
