Only thing is opening it up using the gilksy method, it's not permanent, might last a month, but at least you can use that time to back everything up and put it into a new PS3.
I just kept doing it to my PS3 after about the 3rd or 4th time doing it (got about 3 months out of it) I was screwing in one extremely important screw and the head snapped off half way in the hole -_- couldn't do anything about it, put it all back together it just immedialty over heated (my god that fan screams loud) and was pretty much the end of it. Bought a Slim been going 2 years strong, great machine.
My advice, do the gilksy method, back up your PS3 on a HDD and just keep playing your PS3 normally (saving often). It'll probably YLOD a couple more times but just keep doing it until the new Slim PS3 releases (it's almost garuntee to have a nice price cut, the 16GB should be dirt cheap).
