That entry will definitely be revised when the new edition comes out, since nauseous has now regained this meaning, a change that has been widely noted and commented on. Merriam-Webster’s Dictionary of English Usage says firmly: “Any handbook that tells you that nauseous cannot mean ‘nauseated’ is out of touch with the contemporary language. In current usage it seldom means anything else”. The new edition of the American Heritage Dictionary concurs: “Since there is a lot of evidence to show that nauseous is widely used to mean ‘feeling sick,’ it appears that people use nauseous mainly in the sense in which it is considered incorrect”.
Arguing against popularly acceptable usage of words is pointless pedanticism.
