The module in question here, ip_queue, is supposed to be loaded when
the netlink_firewall protocol is requested:

MODULE_ALIAS_NET_PF_PROTO(PF_NETLINK, NETLINK_FIREWALL);

# modinfo ip_queue | grep alias
alias:          net-pf-16-proto-3

Not sure if that works as expected. Someone needs to try that.
