And on further reading, I can't really see how it makes a difference
for speed; the #ifdef'd code is only at probe time, and results in a
sc->sc_fifolen =3D 32, but nothing that I can see affects the speed or
the frequency (like is done for the HAYESP).
Likewise, comspeed() takes a type argument that goes unused, even if
sc_type were set differently for 16650, which it isn't.
Is the 16650 support incomplete?
