Issue with lm-sensors on n54l

Problem:

At least on Debian Wheezy with 3.x kernel sensors doesn't work properly.

How it looks:

$ sensors

k10temp-pci-00c3

Adapter: PCI adapter

CPU Temp:     +32.5°C  (high = +70.0°C)

                       (crit = +100.0°C, hyst = +95.0°C)

Ok, let's fix it for debian.

1. Compile and install https://github.com/fetzerch/hp-n54l-drivers
2. If sensors output is still too small then check if sp5100_tco is loaded (lsmod | grep sp5100). Try to unload module (rmmod sp5100_tco) or blacklist it. Temperature (i2c-piix) or watchdog (sp5100_tco), your choice. More info
3. ...
4. Profit!

For Ubuntu:

1. Add this ppa and install hp-n54l-dkms package.
2. Done.

Final result:

$ sensors

                       (crit = +100.0°C, hyst = +95.0°C)
