Below is my final attempt at documenting my problems using the latest stable
ppp/netgraph combo with my DSL modem and 3Com 3c905C-TX ethernet card: 

Looks like the NGM_PPPOE_<11> (hook "M-^HM-^V^H^Hh ^K^H")  string
no longer bears any resemblance to the session id bytes.  

Sorry for not making sure all the text is wrapped  properly, but I
figure that would make it only harder to read.
