Kernel Source

["Mariano F.co Bení­tez Mulet"]

Hi all.
I'm a new user of Ubuntu and I have to say my first impression was great.
I'm running it right now in a Medion 40100 laptop, which isn't really 
popular and made me fear there was no compatibility at all.
I didn't have problems enabling the nVidia hardware rendering nor 
detecting any of the components of my computer.
There's only one I need to work around to.
My built-in wireless  card (Intersil's Prism Nitro) has to be flagged as 
"enabled" or by default it won't work. This is done in windows through 
some buttons found above the keyboard.
Now, I've seen some drivers (originally written for Acer laptops but 
hacked for Medion as well) that are suitable and would fix  my problems. 
(http://home.conceptsfa.nl/~revdmeer/md40100/#wirelesslan)
But, of course, for compiling and intalling these drivers I need the 
kernel-source which is:
"cat /proc/version
Linux version 2.6.8.1-2-386 (buildd at mcmurdo) (gcc version 3.3.4 (Debian 
1:3.3.4-9ubuntu5)) #1 Sat Sep 18 09:49:53 BST 2004"
I've looked around and I haven't found it.
Does anyone of you know where could I take this source from?

Thanks in advance for your support.
