I have a CentOS 5 server I can boot into the stock kernel just fine, but when I try kernel-xen, it gets stuck here: http://i.stack.imgur.com/wAI20.png

When I try adding no-bootscrub to the kernel command line, I get this and a reboot: http://i.stack.imgur.com/yy84r.png

Does anyone know where I can go from here?

This looks like you need to exclude a certain memory range. Do your get any hint about that when booting the stock-non-xen-kernel? Please add some details about the hardware of your server. –  Nils Apr 24 '13 at 8:56
