Description of problem:
When a dialup connection is torn down, a spurious error message
appears in /var/log/messages.

Version-Release number of selected component (if applicable):
modutils-2.4.25-13

How reproducible:
Always

Steps to Reproduce:
1. Estabilish a dialup connection.
2. tail -f /var/log/messages
3. Tear the connection down
  
Actual results:
the message

  modprobe: Can't locate module ppp0

appears before pppd exits.

Expected results:
No such message.

Additional info:
The following lines appear in /etc/modprobe.conf.dist

  alias ppp0 ppp
  alias ppp1 ppp

but there is no ppp.o module nor an alias pointing to it. Pointing
the aliases to ppp_generic gets rid of the spurious message, but I
am not sure of the ramifications (although it still works).
