I don't get that with -I (just with -S).  It pretends to work OK; just bad data,
which might be related to the bogus temp. seen in BIOS setup screen.

I get:

ichsmb0@pci0:1:1:       class=0x0c0500 card=0x0c111458 chip=0x00e410de rev=0xa1 hdr=0x00
    vendor   = 'NVIDIA Corporation'
    device   = 'nForce PCI System Management'
    class    = serial bus
    subclass = SMBus

It looks like I got at least one correct driver (ichsmb) in the kernel
and that you didn't.  I don't know what to make of the different "device"
strings, or whether that's from the kernel or the MB.

I see a couple more SMB things in /sys/conf/NOTES that don't sound
necessary, but I'll probably try; namely, 

options 	NETSMB			#SMB/CIFS requester
options 	LIBMCHAIN
options 	LIBICONV
options 	SMBFS			#SMB/CIFS filesystem

Here's what I've got now:

device  smbus
device  smb             # requires smbus
#options ENABLE_ALART	# Control alarm on Intel intpm driver [machine=i386]; Not a typo!
device  iicbus
device  iicbb           # requires iicbus

device  ichsmb
device  ic
device  iic
device  alpm
device  amdpm
device	intpm           # requires smb
device  viapm
device  pcf
