where to find kernel-devel-2.6.18-1.2869.fc6 ?

edit

Hello, we need a very old kernel-devel package kernel-devel-2.6.18-1.2869.fc6.x86_64 to build a kernel module for an old system. However we couldn't find it in archive.fedoraproject.org. Could any one hint us where to get it ?

BTW, we could find kernel-devel-2.6.18-1.2798.fc6.x86_64.rpm in the archive. However the built module binary with that doesn't work with 2.6.18-1.2869.fc6. Apparently 'struct module' had changed btw these versions.

Thanks much in advance !
