Compiles and seems to run on my TYAN Tomcat K8E S2865 BIOS V3.02

nfsmb0: <nForce2/3/4 MCP SMBus Controller> port 
0xfc00-0xfc1f,0x1c00-0x1c3f,0x1c40-0x1c7f irq 20 at device 1.1 on pci0
smbus0: <System Management Bus> on nfsmb0
smb0: <SMBus generic I/O> on smbus0
nfsmb1: <nForce2/3/4 MCP SMBus Controller> on nfsmb0
smbus1: <System Management Bus> on nfsmb1
smb1: <SMBus generic I/O> on smbus1

rev=0xa3 hdr=0x00
     vendor   = 'NVIDIA Corporation'
     device   = 'nForce4 PCI to ISA Bridge'
     class    = bridge
     subclass = PCI-ISA
nfsmb0 at pci0:1:1:        class=0x0c0500 card=0x286510f1

     vendor   = 'NVIDIA Corporation'
     device   = 'nForce4 SMBus'
     class    = serial bus
     subclass = SMBus

Dont have any apps that can talk to it as mbmon doesnt understand this chipset

[tyan-1u]#  mbmon -S -s0 -d
No SMBus HWM available!!
InitMBInfo: Unknown error: 0
[tyan-1u]# mbmon -S -s1 -d
No SMBus HWM available!!
InitMBInfo: Unknown error: 0
[tyan-1u]#
