Just some remarks:

 - i don't use PPP in any of my i4b setups (yet), i only use it for
   testing this and that. In my test setups, i cannot reproduce this
   bug.

 - i have no idea when this occurs or what might be the cause.

 - the ISDN parts of i4b seem to have nothing to do with this bug,
   it seems to be a failure inside either i4b_isppp.c or if_spppsubr.c
   or both.

IMHO, what you are trying to do is the only way to solve this problem,
as someone who is _able_ to reproduce the problem should become a PPP
expert, understand why what is happening and then fix the problem in
the best possible way.
