Yes - that's probably the only mod you'll need. If you connect the +5
side of the resistor to one of the +5 lines on the UARTs port (pins
3,6,11,14).

Adding or removing the tweener has no impact on the network card.

You want to make sure that the gumstix boots. I'd then setup the jumpers as per
http://docwiki.gumstix.org/Robostix_gumstix_ISP

and run uisp to make sure it can detect the ATMega128. I'd then at
least program the fuses for standalone operation and download the
Flash-LED.hex and make sure that the LEDs flash properly.
