The 2200 firmware doesn't support the MS IOCB interface the driver 
uses to issue CT commands to the SNS.  Basically, I had to 
forward-port some code from the 6.x driver to get the SNS calls 
to go through.  I've had several machines (mixture of 2200s/
2300s/others with loop and fabric connections) running with this
patch for the past week.
