When netstat(1) was changed to use a sysctl() interface instead
of peeking at /dev/mem the task was never completed.

E.g. netstat -r doesn't print the refcnt and pksent columns.

Destination        Gateway            Flags    Refs      Use    Mtu  Interface
10.24.5/24         link#1             UC          -   wm0

and it segfaults when using the -P option. Reason is that it doesn't
open then kvm interface anymore but relies on it when printing
the data (that part hasn't been changed yet).

And all this was pulled up to netbsd-4.

Run netstat -rn or netstat -P xxx on a netbsd-4 system.
