In some K2/100s, the mechanical tolerance buildup is such that the KPA100
heatsink may be *extremely* close to the 20-pin connector on the DSPx
module.  If the heatsink contacts the connector, and if the anodization is
scratched or otherwise fails at the point of contact, a short could occur.
This is the primary reason for the foam in the K2/100 installation.
