I am curious... Especially about the GPS on a pin.... You're
obviously using it for timing signals... Can you tell us more about
the GPS itself? I may need to bring in a GPS signal at some point.
(Our guidance system is still in conceptual; we don't know which way
to go... GPS is the buzz, but good old fashioned compasses are more
accurate for what we do....)

I am working with the TSDIO24, the add-on 24 GPIO board. The docs
say I should get IRQ 5, 6, 7, and 9 by writing a 1 to one of the
control registers.... Alas, I get nothing. Nada. Zilch.
I get 0 counts in /proc/interrupts... So I have put that on hold,
since we plan to use the 7300 and haven't got ours yet, but I'd
still like to know if it is the hardware or if my code is broken
somewhere.
