 This is cheating -- a 5th family processor ought to support wp. Some
startup code might rely on this fact and may allow a kernel compiled for a
486 or a 586 to boot on your machine. You need to be careful when
preparing any patches -- I'd suggest overriding the family to be "3" for
"NexGenDriven" CPUs.
