Can't find kernel-source package?!

[James Titcumb <james@total-carnage.org>]

After 2 days of googling and trying various APT mirrors, I simply cannot 
find a kernel-source package that works for me.

My current mirror  is http://debian-amd64.alioth.debian.org/pure64/ 
sarge main non-free

I am using Debian 2.6.10-amd64-k8 (sarge) distro... I can find the 
kernel-headers-2.6.8-10-amd64-k8, but no-where can i find the right 
source package...

An "apt-get install kernel-source" will give me the following possible 
packages...
 kernel-source-2.6.9 2.6.9-5
 kernel-source-2.6.8 2.6.8-13
 kernel-source-2.6.10 2.6.10-5
 kernel-source-2.4.27 2.4.27-8
 kernel-source-2.4.26 2.4.26-6
 kernel-source-2.4.25 2.4.25-3
 kernel-source-2.4.24 2.4.24-3
 kernel-source-2.2.25 2.2.25-3

And as far as i can see, the amd64 arch package isn't there....

Anyone know where to find this rogue package?

Thanks,
James
