A little heat won't kill the Atmel; it should be fine. Now, having it wired backwards MIGHT have caused a problem (voltage on the wrong pin could kill it) but since it would just be low voltage from your parallel port, I still think the Atmel is fine.
If you are curious, and want to pay for shipping both ways, you can mail me your Atmel and I'll try programming it. If it is indeed dead, I'll sell you a preprogrammed replacement for cheap. PM me if interested.
