2 layer board? The clock is routed in the middle of a GND plane and has one below and a power plane above. And there is GND stitching around the edges. While I don't have access to FCC testing facilities here I'm reasonably sure that a 32 MHz clock won't cause any grief. It could be different if the 300 MHz hash clock was route all over the place.

Was the comment about "insane power supply" in that other thread aimed at mine? I'd like to know if someone else said that.
