Did you kldload all of these from the command prompt?  The problem seems to
crop up when one (or more) modules which are dependancies for others are
loaded statically in the kernel, and the others are loaded dynamically.  The
dynamic loader doesn't see that the module is already present, and tries to
load it again.  (For PPPoE, the problem manifests when you only have
'options netgraph' in your kernel.  This forces ppp to try and load the
other ng_* modules dynamically and things fall apart.)

I imagine this is because of 'device miibus', a dependency of both.
