I recently had a networking problem myself, where only pings came 
through from domU to the physical network. I had to turn off tx checksum 
offload with ethtool. I integrated it in the xen-network-common.sh 
script, so maybe this patch will help you too?!
This patch modifies the last line in the "add_to_bridge ()" function:

--- scripts/xen-network-common.sh       2008-05-12 15:22:52.000000000 +0200
+++ scripts/xen-network-common.sh.modified      2008-05-12 
15:23:41.000000000 +0200
@@ -124,5 +124,6 @@
    fi
    brctl addif ${bridge} ${dev}
    ip link set ${dev} up
+    ethtool -K ${dev} tx off
}

Hope it helps,
