The important thing here is the opcodes that changed their semantics between 2.4 and 2.5. There is the YIELD opcode which is probably the one that you're referring to; in 2.5 it pushes a result on the value stack, but in 2.4 it didn't. There is also one of the IMPORT opcodes, which pops one more argument from the stack in 2.5. So the magic version number in PyPy should be changed to 2.5's at the same time as these two opcodes change their semantics in PyPy's compiler and in pyopcode.py.
