The ppp driver, even if you put it into the kernel, enables the module
loader. This is because the PPP Compression protocol interface is
designed to be loaded as a module __ONLY__. There is no way (logically)
to put the compression protocols into the kernel.
(There are a couple of technical reasons and one legal reason for this
decision.)
If you don't load the compressors (bsd-comp.o, ppp-deflate.o, or
pred1-comp.o) then the fact that the ppp driver exports some symbols is
insignificant.
The compression modules do not make references to the procedures which
you listed. They will call procedures called "ppp_register_compressor"
and "ppp_unregister_compressor" and possibly reference the CRC-16 table
in the PPP driver.
If it will help isolate the appropriate sequence during the boot
sequence, you may use the program 'logger' to write messages to the
system log file. I would suggest that you put some trace messages into
the log so that you can tell which operation is generating these events.
Just having the messages means nothing in and of itself without knowing
what is causing them.
