I guess your only option is to get boot2 file from a system which predates GCC 3.4 and install in on broken boxes. I am trying to find the likely cause of this failure. The very first idea I managed to think of is that your problem is yet another fallout from new GCC unit-at-a-time optimisation mode. Could you please test an attached patch and report results here?
