[lm-sensors] "No sensors found!" on Intel Entry Storage System SS4200

I am using an x86 ethernet NAS device with a preloaded custom Linux

I replaced the OS with a stock debian kernel from another machine.

Linux debian 2.6.26-2-686 #1 SMP Sun Jul 26 21:25:33 UTC 2009 i686

Everything works minus the temperature sensors and LED control, both
worked using the original proprietary software interface.

The manual indicates the following fan controller is used:

sensors-detect apparently finds this chip, and modprobe is able to load
the dme1737 driver. (see attachments). Syslog shows nothing exceptional.

"Probing for `SMSC SCH5027D-NW'...Success!
    (confidence 6, driver `dme1737')"

It's not until "sensors" that I see a problem:
"No sensors found! Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are."

Now my question is, is this user error, or is there an incompatibility
in the sensors program with the dme1737 driver?

I'm not afraid to try and debug the code myself if someone could set me
on the right path.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

We can start with probing for (PCI) I2C or SMBus adapters.
Do you want to probe now? (YES/no): 
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 0000:00:1f.3: Intel 82801G ICH7

We will now try to load each adapter module in turn.
Module `i2c-i801' already loaded.
If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.

We are now going to do the I2C/SMBus adapter probings. Some chips may
be double detected; we choose the one with the highest confidence
value in that case.
If you found that the adapter hung after probing a certain address,
you can specify that address to remain unprobed.

Next adapter: SMBus I801 adapter at 0400 (i2c-0)
Do you want to scan it? (YES/no/selectively):

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `dme1737' (should be inserted):
  Detects correctly:
  * Bus `SMBus I801 adapter at 0400'
    Busdriver `i2c-i801', I2C address 0x2e
    Chip `SMSC SCH5027D-NW' (confidence: 6)

Driver `coretemp' (should be inserted):
  Detects correctly:
  * Chip `Intel Core family thermal sensor' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue: 

To load everything that is needed, add this to /etc/modules:

#----cut here----
# I2C adapter drivers
# Chip drivers
#----cut here----

Do you want to add these lines automatically? (yes/NO)
