Here's my (working) .config for 2.6.31-rc8:
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/config-2.6.31-rc8-rebase-master-no-highpte

Sorry I don't have the 2.6.31-final .config online atm.

That's for 32bit PAE. It's originally based on some 2.6.29 fedora kernel
.config, and changed many times pretty randomly after that.. good luck :)

You could also grab http://fedorapeople.org/~myoung/dom0/ kernel and
extract the .config from them..
