Subject: Add a new Linux kernel config file -xen [NB: no 0 or U suffix] that
 builds a wide selection of modules, more in keeping with distro kernels. It
 can be used as both a dom0 and domU domain kernel. It is not built by default
 as it takes ages, but should be in install tar balls and the demo CD.
