Thanks to Clifford Kite for the suggestions. What ended up solving my
problem with PPPD never accomplishing LCP negotiation was traced to a
inappropriately configured serial port.
My serial port uses a 16550AFN UART which was erroneously detected as 16750.
Using setserial, I set it to 16550V2 (note: 16550A does not solve the
problem for me). Now PPPD connects like a champ. Thanks again.
