Download the two files into some directory, then run "make" in it.
You may have to install the linux-headers package first, and possibly
the C compiler (gcc) and/or make.

After make succeeds, run "sudo make install" followed by "sudo modprobe -r coretemp"
and "sudo modprobe coretemp".

Something like

mkdir coretemp
cd coretemp
wget http://roeck-us.net/linux/drivers/coretemp/coretemp.c
wget http://roeck-us.net/linux/drivers/coretemp/Makefile
sudo apt-get install make 				# if necessary
sudo apt-get install gcc 				# if necessary
make
# Note: make will likely fail and tell you the missing headers, such as 
#make: *** /usr/src/linux-headers-2.6.35-25-server: No such file or directory.  Stop.
#make: *** [modules] Error 2
sudo apt-get install linux-headers-2.6.35-25-server	# or whatever linux version you run
make
sudo make install
sudo modprobe -r coretemp
sudo modprobe coretemp
