I haven't tried switching regularly between Xen/non-Xen kernels but is
it possible you might need a separate iptables config for each setup?
In non-Xen mode your device is probably as simple as eth0, eth1, etc,
but in Xen mode you have to consider xenbr0, peth0, vif0.0 and such
depending on your xend-config.sxp setup.

Try turning off iptables while in Xen mode to test..
