Subject: [PATCH] MicaZ's CC2420 Transmit (?) has a problem where it's writing
 bytes to the SPI bus, but then the SPI bus gets disabled.  This sends
 Atm128SpiP into an infinite loop.  This version ensures the SPI bus is
 enabled before trying to write to it, but the real culprit needs to be
 tracked down probably inside of CC2420TransmitP.
