Practically speaking System.map is often wrongly installed. Additionally
Keith Owens has (sensibly I think) refused to support this sort of
thing.

This would be OK for us, iff it was on by default. We want to avoid

because it's not just useful for kernel profiling.

Currently it's just a matter of install the module and go, which is
undeniably very useful.
