No, nothing for ppp (or PPP)

Yes:
alti:/etc/modutils# less ppp
alias /dev/ppp ppp_generic
alias char-major-108 ppp_generic
alias tty-ldisc-3 ppp_async
alias tty-ldisc-14 ppp_synctty
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate
and /etc/modules.conf is the same:
...
### update-modules: start processing /etc/modutils/ppp
alias /dev/ppp ppp_generic
alias char-major-108 ppp_generic
alias tty-ldisc-3 ppp_async
alias tty-ldisc-14 ppp_synctty
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate
What does this mean? I downloaded the kernel as a .deb from debian.org.
I installed it (IIRC) with Kpackage or with dpkg.
I can't recall whether it asked me any questions about what to include when I
installed it, or not.
As a check, I just uninstalled my older 2.4.16-k6 kernel (which I don't
normally use any more) and reinstalled it with
dpkg -i /<path>/kernel-image-2.4.16-k6_2.4.16-1_i386.deb
the only questions it asked me were whether I wanted to use Lilo (no).
It gives exactly the same results for the ppp modules as the 2.4.18 kernel
(above).
Kppp dials my ISP and makes connection as it should - just that it isn't
communicating with Kmail or browsers.
When I boot off the bf2.4 kernel on the floppy, I got no response to
lsmod | grep ppp before I tried dialling my ISP, but kppp dialled
OK and communicated with Kmail successfully and now I get :
alti:/home/cr# lsmod | grep ppp
ppp_deflate 38944 0 (autoclean)
ppp_async 6464 0 (autoclean)
ppp_generic 18728 0 (autoclean) [ppp_deflate bsd_comp ppp_async]
slhc 4432 0 (autoclean) [ppp_generic]
So, I'm a bit puzzled.

In fact, I am using the 2.4.18-1-k6 kernel (I was a bit sloppy quoting it
before, sorry). I also have the 2.4.16-k6 kernel installed, it gives the
same results so far as ppp is concerned. I only have disks 1 and 2 of Woody,
since all the packages I want are on those two disks (except, IIRC, Kppp
which I downloaded off debian.org). It seems kernel images are on disk 1,
packages on disk 5.
But anyway, it looks as if the k6 kernel I've got *should* do ppp OK, if
set up right.
