Could be broken env. variables in OF. Can you try using the same combo as if your were updating the firmware ? I think it's something like powering up the book with cmd-power with the power button kept pressed until you hear a tone. I think this cause it to reboot on a backup copy of OF. If this cause it to double boot, then try doing the cmd-opt-P-R or O-F combo on the second boot. Ben.
