I have a server running CentOS 5 and when yum update is run and a new kernel is installed and there are more then 3 kernels installed the oldest ones are removed. Anyway to achieve this with CentOS 4?

if you want process yum in centos 4
try like this update your lib and python 
# rpm -Uvh http://mirror.centos.org/centos/4/os/i386/CentOS/RPMS/libxml2-2.6.16-10.i386.rpm
# rpm -Uvh http://mirror.centos.org/centos/4/os/i386/CentOS/RPMS/libxml2-python-2.6.16-10.i386.rpm
# rpm -Uvh http://mirror.centos.org/centos/4/os/i386/CentOS/RPMS/python-elementtree-1.2.6-5.el4.centos.i386.rpm
