You need to send correct commands to firmware. Plz check 
http://www.coreboot.org/AMD_IMC  for a summary. Then I would say the interface 
did not change much, so looking into some agesa code will tell you how to 
program stuff there (there are files like imcEnv.c iirc) I need run now, plz ask 
if you want more info.

Also, you will need to enable the IMC and load firmware. The agesa has some 
straps override for this. You just need to place the imc.bin in cbfs  on right
