Maybe you MoBo has some other Power Manager other than nForce3. I did
try mbmon, and even in ISA mode it cannot find any device:
gaia::root ~ [647] mbmon -I
No ISA-IO HWM available!!
InitMBInfo: Unknown error: 0
gaia::root ~ [648]
From pciconf:
none0@pci0:1:1: class=0x0c0500 card=0x813f1043 chip=0x00e410de rev=0xa1
hdr=0x00
vendor = 'NVIDIA Corporation'
device = 'nForce PCI SMB Controller'
class = serial bus
subclass = SMBus
