Monitor CPU temperature in a Supermicro X6DH8-XG2

Dear Srs,

I need to get the CPU temperature in a Supermicro X6DH8-XG2 motherboard, this is the link for key features:

http://www.supermicro.com/products/motherboard/Xeon800/E7520/X6DH8- XG2.cfm

According with the page specs, X6DH8-XG2 seems to have some thermal monitoring chip/hardware:

    * Monitoring for CPU and chassis environment
    * CPU thermal trip support
    * Thermal Monitor 2 support

When running lm-sensors 2.10.1-3 (with libsensors3) on a Debian Etch box I get:

# sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

This is the output for "sensors-detect":

======================================================================== =================

# I2C adapter drivers
# Chip drivers
# Warning: the required module lm93 is not currently installed
# on your system. For status of 2.6 kernel ports check
# http://www.lm-sensors.org/wiki/Devices. If driver is built
# into the kernel, or unavailable, comment out the following line.
# no driver for Nat. Semi. PC87427 Super IO Fan Sensors yet
======================================================================== =================

Debian is using Etch default kernel, 2.6.18-6-686-bigmem, i2c-i801 modules loads correctly but lm93 isn't available:

# lsmod | grep i801
i2c_i801                8236  0
i2c_core               20448  4 eeprom,lm83,i2c_dev,i2c_i801

# modprobe -l | grep lm93
# modprobe lm93
FATAL: Module lm93 not found.

I have also tried looking at ACPI info into /proc, file "/proc/acpi/ thermal_zone/THRM/temperature" but isn't not available:

======================================================================== =================
# find /proc/acpi
======================================================================== =================

Trying with IPMI I get this error:

======================================================================== =================
# ipmitool sdr elist
Could not open device at /dev/ipmi0 or /dev/ipmi/0 or /dev/ipmidev/0: No such file or directory
Get Device ID command failed
Unable to open SDR for reading
======================================================================== =================

And the device appears correctly:

======================================================================== =================
# stat /dev/ipmi0
  File: `/dev/ipmi0'
Size: 0 Blocks: 0 IO Block: 4096 character special file
Device: dh/13d  Inode: 8455        Links: 1     Device type: fd,0

======================================================================== =================

What can I do to get the CPU temperature in this motherboard? Thanks!!
