Well, I don't own an MP3 but my Mazdaspeed is doing the same damn thing. I actually just got off the phone with Racing Beat and asked him if those urethane bushings were available for sale. He said they were not for sale to the public and then put me on hold to talk to his manager. When he came back, he said that they were expecting a set in the mail from Canada (way to go, newf) and that their cheif engineer was going to take a look at them and talk to Mazda about trying to offer a urethane bushing to the public. He suggested the current fixes (grease and new bushings) for the next couple of months. As far as staying updated on the situation, he said this forum (updates from us pesky people) and to call back in the following weeks to months. So...hopefully a solution is in sight.
