hmm RedHat enterprise like Xen kernels, like Fedora, Scientific Linux, 
CentOS, are all PAE enabled kernels, and it is not easy to build a PAE not 
enabled kernel to be used in a install environment... because
I just took hte initrd and vmlinuz  from the install images since
initrd has inside the install facility...
thanks though
