For Yahoo and Bing I will still keep the meta keywords, though it's likely they ignore them as well.
Bing's Duane Forrester posts here under the name "bingdude". He recently confirmed that Bing DOES use the meta keyword signal:
meta keywords is a signal. One of roughly a thousand we analyze. Getting it right is a nice perk for us, but won't rock your world. Abusing meta keywords can hurt you.
