The GOS units are x86 based. I don't know what/who/how etc, but my understanding is that you can get to a "console" from the serial port.
I know enough to follow what you were saying, but not enough to even come close to doing. I know that David has some knowledge in that stuff (beyond mine for the software ends of things), and from conversations I have seen here on the forum, others who appear to have knowledge beyond that. I hope they will get involved.
