NVIDIA failure

It appears that my Macbook Pro was manufactured in august 2007.

Serial number: W87340ZAX91

I bought it on e-bay in april 2011.

The original receipt was thrown away when normal warranty expired, nobody was aware at the time of the NVIDIA issue to come.

Can I still benefit from a repair free of charge as described below? Thanks

"Apple has determined that some MacBook Pro computers with the NVIDIA GeForce 8600M GT graphics processor may be affected. If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within four years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty."

Thanks
