Yep. FC4 is lacking it currently, due to some changes that
happened upstream which cause problems when you want to register
netdump & netconsole at the same time. (plus it needs a little
rediffing). Hopefully it'll get fixed up in time for the FC4 final
release. If not, it'll reappear in an errata soon afterwards.
