 Here are my results with a Supermicro PDSMi MB (Intel E7230 (Mukilteo) 
 Smithfield chipset,  ICH7R + PXH-V + Intel 82573V)
 
 7.0-CURRENT #0: Thu Jul 27 12:28:34 EDT 2006.
 
 The controller is detected:
 
 ichsmb0: <Intel 82801GB (ICH7) SMBus controller> port 0x1100-0x111f irq 
 19 at device 31.3 on pci0
 ichsmb0: [GIANT-LOCKED]
 smbus0: <System Management Bus> on ichsmb0
 smb0: <SMBus generic I/O> on smbus0
 
 However communication does not seem to work:
 
 # smbmsg -p
 Probing for devices on /dev/smb0:
 Device @0x30: rw
 Device @0x32: rw
 ^C
 
 ichsmb0: device timeout, status=0x41
 ichsmb0: device timeout, status=0x41
 ichsmb0: device timeout, status=0x41
 
 I also tried running mbmon using SMB, however this is the result:
 
 # mbmon -S
 No SMBus HWM available!!
 InitMBInfo: Unknown error: 0
 
 Without any options, i get bogus temp values:
 
 # mbmon
 
 Temp.= 208.0,  0.0,  0.0; Rot.=    0,    0,    0
 Vcore = 3.62, 3.62; Volt. = 3.62, 5.21, 11.80,   1.13,  2.09
