Hello,

But in dmesg shows:
=====================================
amdpm0: <nForce SMBus Controller> port 0-0x1f,0xec00-0xec1f irq 23 at device 1.1 on pci0
amdpm0: could not map i/o space
device_attach: amdpm0 attach returned 6
=====================================
I think, I might have to change the PCI registers from 0x14 to 0x50 and/or (not sure) 0x54, which I haven't done on this part yet. I hope, I have the right PCI registers number (found in google). I am going to try add two PCI registers (not sure how to do it yet) and I want to know how should I test with SMBus to make sure it works? Thanks!

Changed from 0x14 to 0x50 looks like it works without throw any error.
Update dmesg shows:
=====================================
amdpm0: <nForce SMBus Controller> port 0x5000-0x501f,0xec00-0xec1f irq 23 at device 1.1 on pci0
smbus0: <System Management Bus> on amdpm0
=====================================
I found a source for nForce2 SMBus[1] and it said that it has two SMBus interfaces (0x50 and 0x54) in a nForce2. So.. I think, I will not hack it more (due to lack of C knowledge) and keep patch (attaching) it by myself for personal. To have one 0x50 seems work for me.
BTW: I am willing to test patch(es) if there has any.
