Reading sensors on Intel DP35DP motherboard can render itself way more 
troublesome than one might expect. I've ran through tons of different
setups with lm-sensors, their drivers and didn't get much results. 
coretemp seems to be the only working thing, but it only gives you the
CPU core temperatures read directly from the CPU alone.

At the time of writing the Internet also seems quiet about this... so
I decided to share one utterly weird approach I found working.

1. Compile your kernel with Intel MEI support
# gzip -dc /proc/config.gz |grep -i mei
CONFIG_INTEL_MEI=y
CONFIG_INTEL_MEI_ME=y
# CONFIG_INTEL_MEI_TXE is not set

2. Fetch the heci-qst reader source code modified by 'Kinta' from Japan
# wget https://www.bondoffamily-net.com/~kinta-chan/techknow/Linux/hardmon/src/heci-qst2/heci-qst.c

3. Compile it against MEI kernel
# gcc -D MEI -o heci-qst heci-qst.c

4. Run and enjoy :)
# sensors && ./heci-qst
coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +27.0 C  (high = +59.0 C, crit = +85.0 C)
Core 1:       +25.0 C  (high = +59.0 C, crit = +85.0 C)
Core 2:       +28.0 C  (high = +59.0 C, crit = +85.0 C)
Core 3:       +28.0 C  (high = +59.0 C, crit = +85.0 C)

**heci-qst(Intel MEI Driver Version)**

Try device name [/dev/mei]
Try device name [/dev/mei0]
CPU_Temp 43.00

ICH_Temp 60.78
MCH_Temp 66.70
CPU_Fan 1141 RPM

Additionally I am mirroring the heci-qst.c file in case some1 would
have issues downloading the original one from Kinta's site.
