mbmon on Dell Precision 670

[Jiri Mikulas]

Hello
I'm trying to get temperature info about CPUs on Dell Precision 670
motherboard.
I have kernel (FreeBSD 6.1-STABLE #0: Fri Jun 30 07:12:09 CEST 2006)
with SMB
device          smb
device          smbus
device          intpm
device          ichsmb

device          iicbus          # Bus support, required for
ic/iic/iicsmb below.
device          iicbb
device          ic
device          iic
device          iicsmb          # smb over i2c bridge

the SMB device is
tnt-new:~# dmesg | grep smb
ichsmb0: <Intel 82801EB (ICH5) SMBus controller> port 0xece0-0xecff irq
17 at device 31.3 on pci0
ichsmb0: [GIANT-LOCKED]
smbus0: <System Management Bus> on ichsmb0
smb0: <SMBus generic I/O> on smbus0

ichsmb0 at pci0:31:3:      class=0x0c0500 card=0x01681028 chip=0x24d38086
rev=0x02 hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801EB/ER (ICH5/ICH5R) SMBus Controller'
    class    = serial bus
    subclass = SMBus

but if  I run mbmon (with SMB support, compiled from ports) I got this
error at the end

tnt-new:~# mbmon
ioctl(smb0:writebyte): Device not configured
Exit 255

tnt-new:~# mbmon -D

Dou you anybody know what should be wrong ?
I found this article http://www.tworoads.net/~srp/hn/monitor420.html
but I don't know how to get value from SMBus slave addresses :(.

Thaks for any help.
