NVRM[0/1:0:0]: Read Error 0x00000100: CFG 0xffffffff 0xffffffff 0xffffffff, BAR0 0xd2000000 0xffffff811846f000 0x0a5480a2, D0, P2/4

That is a graphics Hardware problem.

If this is a MacBook Pro 6,2 (2010) model, there is a recall for this problem:

TS4088- MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video

If you have the MacBook pro 6,2, make an appointment at the Genius bar or your Apple service provider and be sure to PRINT and take a copy of the article (to be sure they know about the program).

Do not leave your Mac to be tested overnight -- the overnight tests will not find this issue. Ask them to run the special VST test while you wait. It ends in a spectacular PASSED or FAILED screen.

If it fails, they MAY replace the logic board, unless too much time has passed. The store manager may be able to make an exception if the time is close.

I'm not clear - have you already had the logic board replaced?

If not, print out your kernel panic (the full text) as well as the Knowledge Base article that Grant mentions and take your machine into your local Apple Store or an AASP and see if they will replace the logic board.

You can see this problem on my video : http://youtu.be/fvKaRJZlVco. With this problem Apple change my motherboard for free. I hope this video will help you.
The problem happens when your macbook pro 15 core i7 mid-2010 passes the intel graphics card to nvidia 330M graphics card with iPhoto for example.
