Oops!
After a little more googling, looks like you need to install kernel-hugemem.
kernel-PAE seems to be for CentOS5.x

[root@fsn1 ~]# yum list | grep kernel-hugemem
kernel-hugemem.i686                      2.6.9-78.0.13.EL       update
kernel-hugemem-devel.i686                2.6.9-78.0.13.EL       update

Where  on CentOS4 system;
yum list | grep kernel-PAE
retunes nothing.
