At first I thought it was something in the network code, too, but after
removing netgraph modules from the kernel and using kernel modules,
it works!  The following is what I have in the config file which works
for 1.4 but not for 1.8 or HEAD:
options         NETGRAPH
options         NETGRAPH_BPF
options         NETGRAPH_ETHER
options         NETGRAPH_IFACE
options         NETGRAPH_KSOCKET
options         NETGRAPH_PPP
options         NETGRAPH_PPPOE
options         NETGRAPH_PPTPGRE
options         NETGRAPH_SOCKET
options         NETGRAPH_TTY
options         NETGRAPH_VJC

On 1.8 or HEAD, it doesn't work either when I compiled these in the kernel
AND load the rest of netgraph modules via kldload.  So I guess this is
either something is not available when netgraph modules are loaded,
or the order in which modules are loaded.

Cheers.
