It depends :)

Some xen-hosting providers only allow users to only use their kernel.
If you're one of those hosting providers, then you'd want to compile
everyting built-in. If you want to put kernel on dom0, you'd probably
want to go this route.

Some distro maintainers (e.g. Redhat) opt for
almost-everyting-is-a-module. One of the reasons is to avoid wasting
memory from unused drivers. If you want to user kernel on domU (loaded
with pygrub), you'd probably want to go this route.
