Help me make lm-sensors work?

I want to use a temperature plugin but am running into several problems...
My board is Asus P8B75-M LX PLUS and i'm running 0.4.36 / 2.6.32-5-amd64 and if i do a simple

apt-get install lm-sensors

No sensors are detected
So i manually installed a newer version (lm-sensors 3.3.4) and now i get this message when running

sensors-detect

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)


Driver `nct6775':
  * ISA bus, address 0x290
    Chip `Nuvoton NCT5532D/NCT6779D Super IO Sensors' (confidence: 9)


Warning: the required module nct6775 is not currently installed
on your system. If it is built into the kernel then it's OK.
Otherwise, check http://www.lm-sensors.org/wiki/Devices for
driver availability.

Since i'm still getting the same sensors output

acpitz-virtual-0
Adapter: Virtual device
temp1:        +27.8°C  (crit = +92.0°C)
temp2:        +29.8°C  (crit = +92.0°C)

Which is not the actual temperature, I'm guessing i need to install this nct6775 driver...
I downloaded this driver https://github.com/groeck/nct6775/ but when i try to build it i'm getting this error

compat.h:32: error: I2C_CLIENT_END undeclared here (not in a function)

The only thing i could find online is that i would need to patch the kernel with i2c? Is that true? Is that possible?
I couldn't find how to do that so i'm lost now ...

When sensors-detect runs i see this output

Module i2c-i801 loaded successfully.
Module i2c-dev loaded successfully.

which makes me think maybe this ict is already installed? Maybe i just got the wrong kernel header? I used this command

apt-get install linux-headers-$(uname -r)

Edit:
I got it to compile by adding 2 things to the compat.h

#include <linux/i2c.h>
static unsigned short normal_i2c[] = { 0x290, I2C_CLIENT_END };

I chose 0x290 because it showed up in the sensors detect dialog

Found `Nuvoton NCT5532D/NCT6779D Super IO Sensors'          Success!
    (address 0x290, driver `nct6775')

sensors-detect now doesn't show the warning that no driver was found but the values i get are still the same
The problem is that i don't even know if anything i did makes any sense since i have 0 knowledge about all this stuff

I figured some things out ...
if i do

modprobe nct6775

sensors will show me much more information, i'm not sure yet how useable the values are but some are close...

But when i do

modprobe coretemp
FATAL: Error inserting coretemp (/lib/modules/2.6.32-5-amd64/kernel/drivers/hwmon/coretemp.ko): No such device

I'm getting this error which i guess means my CPU isn't yet supported so my plan is to update the kernel.

And now the 100% OMV related question:
If i use this guide http://linuxg.net/how-to-insta…int-debian-and-derivates/ to update to kernel 3.11.4 will that screw up the OMV configuration?
Will it still boot like it did before ? I currently have no keyboard or screen plugged into the NAS so ....

I just updated the kernel and it still boots and seems to work just fine.
Updating was a bit more complicated than i hoped, had to get a different version of libc6 first which required to add a testing apt source.

The coretemp driver now recognized my cpu and i get plausible temperatures

If anyone knows of any negative side effects that might occur now or later on please let me know.
