This issue has been beat upon quite frequently as of late, ask Mr. Neiberger;) I'll give you a good reason why you might choose auto. Had a large customer who recently installed a 4507 with supIV and 48 port 10/100/1000 cards. The customer was seeing a very large number of input and CRC errors. They hardcoded the ports and tried differant ports and modules, no help. I suggested they try auto and wallah, all errors ceased. Try manual again and the errors reappear immediately.
