here is your error... /boot/xen-3.gz is not the kernel image, it's the xen 
hypervisor itself. 

If you have installed the "linux-xen0-2.6" package correctly, you should have 
a /boot/xen-linux-2.6.12.6-xen file, which is a xen kernel for dom0 and/or 
any domU. So using "kernel = /boot/xen-linux-2.6.12.6-xen" would be correct.

You additionally need an initrd, which normaly exists 
in /boot/xen-modules-2.6.12.6-xen. If it's not existing, you have not created 
it with mkinitrd... In your domU config you have to include the inird with: 
"initrd = /boot/xen-modules-2.6.12.6-xen"

I guess there is also some network settings missing, but maybe it also works 
without them, never tested that really... 

For example configuration files you can take a look 
at /usr/share/doc/xen/examples.

the rest of your setup looks quite well, so if you fixed your domU config, you 
should be able to start the new domU. If not let me know...
