It is hit if you're BIOS sets up ACPI tables. But on a single CPU 
system you shouldn't really notice anything. Even if the code failed, 
it normally just resorts back to 1 CPU. But if it hangs for you or 
something like that since the changes, I'd obviously like to know ;-)

I think it does not consider it at all right now. But there's supposed 
to be a completely new scheduler implemented. I guess this one will 
include affinity? Does anyone know of news on that one BTW?
