Subtle timeing problems?  Whats the speed rating of both parts?

How many address lines does the board really use?  Its possible that if 
some of the address lines were floating that it might work with one part 
but not the other.

How big is your LB image.  Try makeing mutiple copies of the image in 
the rom.  Then it won't matter if the upper address lines float the 
wrong way.
