I flew SEA-SFO-KOA on 1/8 and return on 1/22 with six small lithium camera batteries and was not questioned. I can see where there may be a problem with TSA interpretation as the regulations are being condensed to "two batteries allowed in carry-on"

"New Regulation Bans Loose Lithium Batteries in Checked Luggage and Limits Number Allowed in Carry-Ons
A new regulation, designed to reduce the risk of lithium battery fires, took effect on January 1, 2008. Loose extended-life, spare rechargeable lithium batteries are no longer allowed in checked luggage and passengers are allowed to bring only two such batteries in carry-ons and they must be carried in either the original retail packaging or in a plastic zip-lock bag.
