Thanks a lot Joerg! Checking the circuit indeed revealed that
connection. I would never suspected that! With this info 
it was a piece of cake to get the mega325 running on the 
STK501. Just manually connect reset and sck on the isp
connectors, but reroute mosi/miso to pbt2/pbt3 on the 
Expand1 connector. 

Ruud.
