I can see /dev/smb* now, but I still can't use -S in mbmon.

Have you tried to do the kldunload amdpm yet? It will get FreeBSD crash  
and forced me to reboot. I don't have any debug in my kernel, so I can't  
provide the backtraces. Does amdpm needs the iic* stuff? I remember that  
one of my dead motherboard that use viapm required the iic* stuff.

Cheers,
Mezz
