No. I choosed to install ppp support in kernel and not as module when making
xconfig.
I compiled then ppp 2.3.7 in user space without updating the ppp.c in kernel
to the last one.
Then everytime I wrote a new printk() in /usr/src/linux/drivers/net/ppp.c, I
compiled the kernel again by giving
make dep
make bzImage, etc...
but never did make xconfig again.
Later I even updated the ppp.c in kernel by giving make kernel command after
./configure, when recompiling.
Anyway I didn't get the 3 logs above anymore.

The lsmod command says that
no module is loaded till when the pppd of the two pc build up the
communication.
After that the ppp_deflate and bsd_comp modules are loaded.
They remain loaded after pppd are terminated. I don't know if they get
unloaded.
I'm checking it now.
Moreover I can tell you that when issuing "shutdown -r now", I get the
following logs:

I see. OK. This is interesting.
Thank you.
