Wouldn't it be pretty stupid not to use the APIC of modern systems if available to get all the benefits, like additional interrupts? At least my Asus A7V600 refuses to (net-)boot at all without a somewhat recent kernel *and* APIC enabled in BIOS and kernel because the interrupt routing is completely messed up. I'd rather let all users who have APIC problems report on the list and wait until someone fixes the issue instead of having them shut up and use less advanced techniques instead unless you want to get those "but it works in Windows" discussions going...
