Installing Debian (Potato) did not install kernel source...

[iwrigb@tpg.com.au]

Hi,
  I have just switched from RH to debian, and in the process of 
trying to compile nvidia and creative drivers have discovered that 
the kernel source was not installed. (Due to the fact that the 
drivers could not find moduleversions.h) Is this the usual behavior 
for Debian installs, or did I miss something? 

Regardless, how should I get the kernel source installed and in synch 
with my current kernel? Will "apt-get source kernel" do the trick? If 
so will I then just need to do a "make dep" to allow me to build the 
drivers? (I am yet to do a kernel re-compile, so I am a little bit 
green in these matters ATM)

TIA
Barney
