I just recently downloaded kernel-2.6.15-1.1831_FC4.i686.rpm, rpm'd it and installed it fine. Now I can safely boot to that version no problem. The problem is that I can't find its source files and its not under /usr/src/<Kernel version>. In fact there is no directory named after the new kernel anywere except at /lib/modules/kernel but that doesn't contain the build or source folder.
I need to create a symbolic link from /usr/src/<Kernel version> to /usr/src/linux to install a driver but cant do it because somehow the directory is not there. I have tried searching it but it was nowhere to be seen.

Can anyone help me?
