Hello Jean,

> 1. What is an "lm-sensors user-space adapter"?
    I picked-up this language from the opening paragraph of
Documentation/i2c/dev-interface ...but perhaps "i2c adapter" would be
more correct.
> 2. What motherboard is this?
    It is a proprietary Motherboard with a 915GM Chipset, and an
FW82801FBM Southbridge. 
> 3. Did you have to unhide the SMBus?
    No - is it possible that this would be needed?
> 4. Please provide the output of lspci
    Output is in attachment lspci.txt.
> 5. Is this a vanilla 2.6.14.1 kernel, or are there additional patches
applied?
    It's basically a vanilla 2.6.14 kernel except:
    a. It's running entirely from Ram; initramfs is enabled.
    b. It has boot patches so it can boot from a nonstandard location.
The image is uploaded serially via xmodem using a proprietary bios. But
once booted it should look/act like plain vanilla. 
> 6. Did you try a more recent kernel? 2.6.14 is getting old. You should
be using at least 2.6.14.7.
    I'll try it with 2.6.19 ...not sure how long that would take. 
> 7. Please attach your exact kernel configuration.
    Configuration is attached in file Kernel.config.txt

Thanks,
Patrick
