If you can't do any hardware mods then you're stuck. It isn't an initialisation or software problem.
What is the voltage on the SDA pin when the 12V peripheral feed is disconnected? Does the peripheral board get power from anywhere else?However, I have tried completely disconnecting the 12v feed to the i2c peripheral - it makes no difference. The only thing that allows the boot sequence to continue is physically disconnecting SDA at boot time!
