I am having the same issue where I am able to clock all of the data and NSTATUS stays high showing no errors but I never get the CONF_DONE going high at the end of the transfer. I am using an MPC8309 and programming a Cyclone III using PS. Does the file need to be built a certain way for passive serial?

Are you serializing your bits correctly?
The MPC8309 is a big-endian PowerPC, perhaps you are reading 32-bits and sending out the 4 bytes in the wrong order?
Look at the bytes in the .rbf or .rpd file, and then knowing that they are shifted LSB-first, look at the serialized data on your DATA0 FPGA pin, or just look at your code.
