I haven't tried it, but I don't see any reason you couldn't use the wiggler
to bit-bang spi comm to the eeprom.  It'd be pretty slow, but if you don't
have a lot of data to transfer it might be acceptable.  

Why not write a very small program to do the serialization, use the BDM to
load the program, stuff the next serial number in the '332 registers, then
run the serialization program to load and verify the eeproms?
