This is not ENTIRELY true. Certain hangs and crashes can be caused with X, APM, and APIC enabled. I haven't entirely tracked it down yet, but I have seen it on a Thuderbird 800 (FIC SD11), an Soyo Dragon Plus (1800+ XP), and a few others. It goes away if you turn Local APIC's off. This may be related to some video card issues, but I don't yet know.
