Weird. And of course you are using speed 115200, or at least 57600, in
your ppp configuration, right? (just ruling out common
misconfigurations). Check also for IRQ conflicts between your modem and
your NIC. Maybe they're being forced to share an interrupt, and one or
both do not like that.

IMO you'll miss 2.4 if you go back to 2.2, and you'll miss woody even
more, if you go back to potato. There should be no need for that.
yenta is needed only for the *kernel* PCMCIA support. I don't use that
myself, I use a custom 2.4.18 kernel with modules from pcmcia_cs (that
is, I use i82365, not yenta_socket).
What I do is get the kernel-source, pcmcia-source, and kernel-package
packages. Uncompress the PCMCIA tarball, so you end up with a "modules"
directory right under "/usr/src". Configure the kernel with no PCMCIA
support (that's right, disable it completely). Run the usual make-kpkg
kernel_image and, after that, a make-kpkg modules. You should probably
make the rest of the PCMCIA packages, as well, to avoid version problems
with the kernel. See the make-kpkg and pcmcia-source docs for details.
That should give you a pcmcia modules package, with modules from
pcmcia_cs, not from the kernel. Then you'll configure for i82365 again
and, if your problem is yenta, it should be gone.
Hope this helps.
