Ppp opens the tun device at startup. It's only used to read and
write packets to the tun interface. Talking to the modem is a
separate thing.

<my understanding>
I'm no expert in this area, but basically, a PnP OS is one that's
willing to assign resources to PnP cards. If you tell the BIOS that
the OS is *not* PnP, the BIOS will assign them itself.
FreeBSD is *not* a PnP OS as it expects the cards to already know
what resources they're using.
However, FreeBSD needs to know the PnP ID of a given card if it wants
to do interesting stuff with it. There are tables of these IDs in
various places in the source code, so what I suspect you need to do
is boot with the -v option and get the PnP ID then get someone to
update the sources.

The DES stuff will build if /usr/src/secure exists.
