[lug] Newbie tries to make laptop modem work

I am able to report limited success.  Because I couldn't find a
match for my kernel image at http://www.heby.de/ltmodem I installed
the 2.2.19 kernel image, kernel headers, and pcmcia modules.
I fixed LILO.  It boots, but now my cdrom is broken:

$ sudo mount /cdrom
mount: the kernel does not recognize /dev/cdrom as a block device
       (maybe `insmod driver'?)

What's the deal here?  It looks like I'm supposed to insert some
module---anybody know which one?

I then downloaded the matching ltmodem-2.2.19 which led to the
module dependency problems mentioned earlier in the thread, so
I downloaded the source.  The build-deb script didn't work, but
the generic one did.  The install script was in the wrong place
and the autoload script was misnamed, but eventually I got the
modem driver compiled and installed.  Now I come to the success
part:  I was able to dial into the first computer and login.
However, I was unable to establish PPP.  My wvdial experience
is below, as is my kppp one.

With wvdial it does the stuff you see, and then just hangs---I
can't ping, telnet, etc.  I also put the concurrent /var/log/messages
stuff below.  I can't see what's wrong.

With kppp, I make the connection and get a little terminal window
with a "Continue" button.  In the window I enter my username and
password.  At the next prompt I type "ppp" and return, and then
hit the "Continue" button.  I'm supposed to get PPP then, but as
you see from the log below I get a string of garbage, in chunks.

As usual, any help is greatly appreciated.
