Which Kernel headers in Knoppix 3.4?

I down loaded and installed the Knoppix 3.4 CD listed in another forum
( ftp://ftp.tu-chemnitz.de/pub/linux/knoppix-remastered/ ) here and had no problem getting it up and running. However when I try and install the Nvidia drivers for 5600 Nvidia card it has a small problem. No kernel module and no kernel headers.

uname -r tells me
2.6.3


cat /proc/version tells me
Linux version 2.6.3 (root@Knoppix) (gcc version 2.95.4 20011002 (Debian prerelease)) #1 SMP Sun Feb 29 03:18:58 CET 2004

if I apt-get install (as root) kernel-headers-2.6.3
apt-get install kernel-headers-2.6.3
Reading Package Lists... Done
Building Dependency Tree... Done
E: Couldn't find package kernel-headers-2.6.3

So, anyone know which kernel headers this version of Knoppix 3.4 uses?

Thanks

Look in the /usr/src directory. Klaus leaves notes in there telling you where he got his kernel-sources from and what patches, if any, he applied to it. For the record, I'm certain he uses the pristine kernels from www.kernel.org, but he may change his mind and get it from debian, but debian's kernel-sources are patched with additional patches that differs from the pristine kernels in Linus' source tree.
