Really? Here's an example where this is not true (anymore?). In
FreeBSD 4.5RC (-STABLE), last cvsupped 01/20/2001:

address@hidden:/usr/src/usr.sbin/ppp> uname -a
FreeBSD bsdevil.rent-a-wizard.net 4.5-RC FreeBSD 4.5-RC #0: Mon Jan 21 02:26:11 
CET 2002     address@hidden:/usr/obj/usr/src/sys/MYTOWER  i386

address@hidden:/usr/src/usr.sbin/ppp> grep ng_pppoe * 
ether.c:#include <netgraph/ng_pppoe.h>
ether.c:    if (modfind("ng_pppoe") == -1 && ID0kldload("ng_pppoe") == -1) {
ether.c:      log_Printf(LogWARN, "kldload: ng_pppoe: %s\n", strerror(errno));
ppp.8:.Xr ng_pppoe 4
ppp.8:.Xr ng_pppoe 4 ,

Here, ether.c uses the ng_pppoe KLD to provide PPPoE support.
Of course, the code for this is only included when:
  #if defined(__FreeBSD__) && !defined(NOKLDLOAD)
but this is not always the case. I see a _LOT_ of references to
netgraph(3) Ng*() functions throughout the code.

So it may still be necessary to port Net/3 and netgraph(4) to the
Hurd anyway, if we want to be able to synchronize to the most
recent ppp version, right? Of course, we could rely on the current
um-pppd, but, we'll miss pppoe and other goodies them!
