Seems as if all the bases have been covered. Is there any difference between the cards on 6509A and 6509B? Does the 6509 support the "set port host" macro? I believe that it sets spanning tree portfast enabled, trunking to off and PAgP to off. According to Cisco LAN Switching page 314 "..when you enable PAgP (Port Aggregation Protocol) on a link where Spanning Tree is active, Spanning Tree takes about 18 more seconds to converge...." I believe that is also true if spanning tree is set to portfast. I'd suggest comparing the configs of the two switches line by line. How is your VTP domain configured?
