    Let me know when you have something that I can benchmark. I am eager
to see how the perf improves.

   I have put lmsensors on the dual Athlon and the I will try to heat 
them up
a bit to see if indicated temperatures make sense.


                                                                        
                                        Regards
                                                                        
                                        Mike
