Depending on the CPU this might cost a lot more then what the CPU is worth.
Watch ncix's video. Search it on youtube. He tried unbending it but than he broke it XD. I love his videos! He does something after and and fixes it. I don't remember what. I think he just puts it inside the little hole.
I have AMD X4 965 CPU.. But Well if my CPU does not work.. How will i know later on what the Pin has damaged on my computer?
I wouldn't worry about the pin or CPU damaging the PC.
I got lucky-I broke a pin on my Phenom I 9850 X4 and I thought I really blew it. I was so pissed at myself, but I was pleasantly surprised. Evidently it was non-essential and the chip still performs beautifully today.
All you can do is try it and see, but I wouldn't be too concerned with damaging anything, it will probably work or not.
