It appears to deal with the graphics card as it contains entries pertaining to IOGraphicsFamily and com.apple.ATIRadeon9700.  I know that there were some problems with iBooks and their Graphics cards in the past, but are you sure that the computer is an iBook?  Reason is because the highest graphics card in an iBook is a Radeon 9550, and not the 9700.  I know that the 9700 was in late model Powerbook G4's so let me know if this is the case.

It is an ibookG4, so where do we go from here?  Is the graphics card seperate from the logic board or built into it?

No, the graphics card is built into the logic board.  You might try adding a shim to the graphics card to see if that helps.  I know that this was a problem for iBook G4's so take a look at these links and give it a shot.  Other than that, the only thing left is to replace the logic board, which you can get from ifixit.com, ebay, or other places.
