nvidiia kernel patch with the 2.6.15-486 kernel

[Freddy Freeloader <fredddy@cableone.net>]

Hi all,

I think the kernel number in the subject line is the correct one.  
Anyway, it's the kernel for an AMD 64 cpu with the 32 bit version of 
Etch installed.  What I'm looking to do is install the kernel patch with 
module-assistant but it tells me there is no kernel source for any such 
kernel. 

Has anyone done this?  I have used this same kernel on my laptop and an 
ATI video card, but am definitely having problems getting an nVidia card 
to run with this same kernel on a desktop system.
