You can actually get your disk out by forcing a manual eject.
Shut your ps3 off in the back.
Hold you finger over the eject button, and keep it there. Turn on your ps3 in the back, and the fan will whir really loud, like it's doing a fan test, and keep your finger on the eject button until the disc pops out.
I had the light of death, but was able to get my disc out this way.
