Looks like it's found a modem to me.  Symlink /dev/ttyS04 as /dev/modem
and throw minicom or something at it.

That file is actually somewhat useless for diagnosing stuff, but it at
least somewhat indicates things are working.

Actually this is normal.  Until the interface has been initialized with
an IP address, it's not going to appear in the output of
`/sbin/ifconfig` at all, and in some cases specifying the interface
explicitly like `/sbin/ifconfig eth0` is pretty meaningless as well. 
Perhaps you forgot to edit /etc/pcmcia/network.opts?  (hint hint)

If none of this works, upgrade pcmcia-cs to either 3.1.34 or 3.2.3 (my
own notebook just died recently, so I haven't tested the 3.2.x series)
and then post updated syslog output.

Heh.  Not a bad idea.  :)

BTW, you should consider updating pcmcia-cs to 3.1.34 (the latest 3.1.x
version) or 3.2.3 (the latest 3.2.x version).  I've gotten Linux going
on about 30 different types of notebooks and usually any problems I had
would disappear with an upgrade to the latest pcmcia-cs package.  

You might also want to consider _not_ enabling the yenta module in the
kernel if it gives you fits.  On some older chipsets it still kills the
machine.  (You seem to be doing just fine with it tho.  :) )
