the debug, PAE, and xen kernels are from different packages.  To see 
what all is actually installed on your system, you just might do...

    # rpm -qa |grep ^kernel
    kernel-2.6.18-92.1.18.el5
    kernel-devel-2.6.18-92.1.18.el5
    kernel-2.6.18-92.1.22.el5
    kernel-2.6.18-128.1.6.el5
    kernel-devel-2.6.18-92.1.22.el5
    kernel-devel-2.6.18-128.1.6.el5
    kernel-headers-2.6.18-128.1.6.el5

in your case, I'd likely do...

    # yum erase kernel-PAE-2.6.18-92.1.18 kernel-debug-2.6.18-92.1.18 
kernel-xen-2.6.18-92.1.18
