find me where on the PS3 box does it say that you can run Linux on it. if not then you should sue the store you bought it from if they were the ones that told you it has this ability. the case would have too many holes and gray areas and if you are lucky could be dismissed or if not then the judge would see that there is a EULA presented before downloading the update and would rule in Sony's favor. but who these days is going to risk going through a long court case where even if you win still would not be able to fit the bill for the lawyer fees.
