The aes module should be loaded at boot time using modules.conf as you can call it there , once the kernel has loaded it up you can use lsmod to check it's installed and why which point ipsec/openswan should have loaded afterwards. You might want to do some digging if you want to do something else but from what I'm familiar with centos/redhat my have updated the centos district so you probably want to do a yum update to refresh the repo for the bug fix if they have included it
