Just wondering if you ever got the header and the resistor? 0603 is a form factor for a 1/10th watt resistor, so knowing the actual resistance of the part is also necessary to effect this 'upgrade'.
They told me "Its actually a resistor (33 ohm 0603) at R18." I got the resistor, but haven't had a chance to install it (work is nuts and have a lot on my plate right now).
