pppd doesn't need to be taught to create the interface.  Rather it needed
to learn to check for ppp support in a non-stupid way.  The following
patch should do it as well as making pppd do the right thing when
support isn't compiled in, but a module is available.  It should make
things work with a GENERIC kernel.

If someone who actually uses pppd could test it, perferably in both
sceneios, I'll see about getting it commited.
