Yes, you could use LVCool program, or merge the LVCool functionality to
amd-smp-idle. I added place holders for enabling other chips.

Just add functions for enabling north and southbridge, and then fill in 
the idle function. I kind of thought of modifying LVCool, but it was not 
using the Linux PCI API, and was not really suitable for SMP systems.

LVCool is at:
