I have a new kernel (2.6.38-0.rc4.git3.1.xendom0.fc15) at http://koji.fedoraproject.org/koji/taskinfo?taskID=2833991 . This uses the Konrad's devel/next-2.6.38 branch (from http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git ), as I have been having trouble which Jeremy's xen/next-2.6.38 branch. It has the revised xen-netback patches, so doesn't need the hack to /etc/sysconfig/modules/xen.modules that the previous kernel needed to avoid backtraces (indeed the hack stops xen-netback loading with this kernel as the netback_kthread parameter has been dropped).
