FYI everyone -- Dave and others have pointed out to us at Gumstix  
that it looks like the red LED on the robostix was mounted backwards  
on the board, so its polarity is reversed, and being an LED, it won't  
light when voltage is applied by the atmega.  Looks like the  
manufacturer of the LED may have mismarked them, since the little  
green polarity dots on them are aligned the same way on the red LED  
as on the working yellow and blue ones....  In any case, if you enjoy  
de-soldering and re-soldering 0402 LEDs, help yourselves :)  If not,  
looks like on that first batch of boards, the red LED won't work.
