searching for kernel headers 2.6.20-16-386

[Bernard <bdebreil@teaser.fr>]

Hi to Everyone,

On an attempt to install OSS instead of ALSA on my Debian Sarge, an 
error message pointed out that I missed kernel sources and headers on my 
system. OSS 4.1 therefore refused to compile.

My kernel is 2.6.20-16-386. On Sarge, kernels are 2.4..., but, about 18 
months ago, someone had convinced me to switch to 2.6. No problem until 
now, except that I've got to install headers and sources.

'apt-get install linux-headers-2.6.20-16-386' replied that this was not 
found.

'apt-get install linux-headers-2.6.20*' displayed a list of 
linux-headers beginning with 2.6.26...

I suppose that 2.6.20. must still be available some place. Could someone 
tell me where to find linux-headers-2.6.20-16-386 ?

Thanks in advance for any hint.
