"Squiggly Traces" are actually know as Serpentine Traces. These wires are often used to make traces the same length. In high speed signaling, especially when using differential signaling ( http://en.wikipedia.org/wiki/Differential_signaling ). Differential signaling requires the signals arrive at the same time. Take a look at this Sparkfun Forum talking about what they are with a example picture: http://forum.sparkfun.com/viewtopic.php?f=20&t=29396
