Interesting! My assumption was that those were for the instrumentation =
part of this system; I've left the ISDN testing card installed, and it =
also has a port on the back for trigger, clock, etc. that I believe may =
be connected to one of those GPIOs cards.

Is there anything I should printf() within your patch too? Since I can =
get a reliable dmesg now using serial, I can output pretty much =
arbitrary information.
