The rp-pppoe (which I use) has a -s option, which uses a synchronous
mode; from the manpage:

       -s     Causes  pppoe to use synchronous PPP encapsulation.
              If you use this option, then you must use the  sync
              option  with  pppd.  You are encouraged to use this
              option if it works, because it greatly reduces  the
              CPU  overhead of pppoe.  However, it MAY be unreli-
              able on slow machines -- there is a race  condition
              between  pppd  writing  data  and pppoe reading it.
              For this  reason,  the  default  setting  is  asyn-
              chronous.   If  you  encounter bugs or crashes with
              Synchronous PPP, turn it off -- don't e-mail me for
              support!

It might be worth trying on slow machines, although those are the ones
most likely to suffer from the race condition.
