[lm-sensors] No temperature/fan values with 83627THF chip

[Jon Still]

Hi,

I've been having problems with h/w sensors on a Supermicro P8SCi that 
came as a barebones 1U server (Supermicro 5014C-T).

See http://www.supermicro.com/products/system/1U/5014/SYS-5014C-T.cfm
which claims the board has a 83627THF chip.  I can now detect and load the 
module for this chip, but my temperatures and fan speeds are reported 
erroneously.

This is using: sensors version 2.9.0 with libsensors version 2.9.0
on: Linux 2.6.11-gentoo-r8 #1 SMP Thu May 19 19:00:00 BST 2005 i686 

'sensors' gives this output:

The output of 'sensors-detect' is attached.  The sensor hardware is 
definitely working correctly as I get both fan and CPU readings in the 
BIOS.  Also, when I start lm_sensors using Gentoo's init script, it fails 
trying to load smbus-arp, as the module does not exist.  However from 
googling, I'm unsure if this is important or not!

If anyone can help, I'd be most grateful as I'm drawing blanks at the 
moment!

Thanks,
Jon.
