Why???? The SuSE kernel is not meant for Fedora Core 5. If you want a newer kernel for FC5 then use yum, as root from the console or xterm session type;
yum -y update yum ;this updates yum and related packages first which is needed
yum -y update
Reason (example);

Use the tools and packages meant for your distribution and do not attempted to mix rpm packages not for your redistribution.
