Take a look at my example .config files mentioned on troubleshooting section on:
http://wiki.xensource.com/xenwiki/XenParavirtOps 

For example:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.32.15-pvops-dom0-xen-stable-x86_64

That's (originally) based on Fedora 11/12 default kernel .config, so it has 
most stuff as modules..
