[CentOS] PAE Kernel

I have a box running CentOS 5.x 32 bit.  I noticed these kernels are installed.

[root at ns1 log]# rpm -qa |grep kern |sort
kernel-2.6.18-194.11.1.el5
kernel-2.6.18-194.3.1.el5
kernel-2.6.18-194.8.1.el5
kernel-PAE-devel-2.6.18-194.11.1.el5
kernel-PAE-devel-2.6.18-194.3.1.el5
kernel-PAE-devel-2.6.18-194.8.1.el5

[root at ns1 log]# uname -a

This machine only has 1G of RAM.  Should I just remove the PAE kernels?
