See our -xen config files under
linux-*-sparse/arch/xen/configs/xen_defconfig_x86_32

The -xen kernel has pretty much everything compiled as modules, and
should be what most users want. The -xen0 and -xenU kernels are really
just for developers, having a relatively small configuration so they
build fast, and with functions compiled-in rather than as modules so as
to obviate the need to install modules before booting.
The only advantage of using the -xenU kernel over the -xen0 kernel for
guests is that it's a bit smaller. Its still rather larger than the -xen
modularized kernel, though)
