Dump your ASL and look for what the _PCT method returns under your 
Processor object.  It will reference two registers, the control and 
status regs.  Post that ASL and we'll see why register setup is failing. 
  It could be a collision with someone else who has grabbed the SMI port 
or it is not an IO or Memory-based register.
