Terry claims the problem is somewhat masked on systems using more
memory and particular kernel options. Not my words and claims, but
Terry's, however you can try to physically take out memory (if you
have two 256MB modules) or limit it at boottime (into which I don't
believe, personally, but that's my uneducated faith only).
