[KLUG Members] Help with Modem on Debian 2.4.27-2-686

[Green Proc]

Hi, I'm having some problems getting drivers to work for the modem on an
IBM Thinkpad 1400i series (Type 2611-452).

The modem is a Lucent WinModem 56k (rev.01), 11c1:0449 DSP=1

I downloaded and unpacked my kernel-source, and installed the
kernel-headers via apt-get install, copied the kernel config from /boot,
ran make dep, and was able to make the kernel without errors.

Next I downloaded http://www.sfu.ca/~cth/ltmodem/ltmodem-8.31a10.tar.gz
, unpacked and ran their custom ./make_module script.

It succesfully compiled lt_modem.ko and lt_serial.ko, but the module
lt_serial (which requires lt_modem.ko) will not load due to unresolved
symbols:

sophie:/lib/modules/2.4.27-1-686/ltmodem# insmod lt_modem.o
Warning: loading lt_modem.o will taint the kernel: non-GPL license -
Proprietary  See http://www.tux.org/lkml/#export-tainted for information
about tainted modules
Module lt_modem loaded,with warnings
sophie:/lib/modules/2.4.27-1-686/ltmodem# insmod lt_serial.o
lt_serial.o: lt_serial.o: unresolved symbol tty_unregister_driver_Ra6f69efd
....
....
....
lt_serial.o: lt_serial.o: unresolved synmbol tty_get_baud_rate_R580a00fd

I noticed that when the modules compiled they were compiled as for
2.4.27-1-686, which is *NOT* 2.4.27-2-686

I did a rm -rf /usr/src/kernel-headers-2.4.27-1-686 ( the 27-2 was there
), I figured it wasn't needed, I wanted at 27-2 version anyway, cleaned
my source, succesfully went through the configure script, but make
produced incompatable pointer type errors.  At this point I got a bit
upset and went to make a sandwich.

Has anyone resolved this issue (more appropriately ever had the issue to
begin with!) and maybe have a pre-compiled binary for my debain kernel
version?  I've looked almost everywhere.

Does anyone have experience with that particular modem in linux, and
perhaps could suggest a distro that it works with?

The instructions in the source package for ltmodem-8.31a10.tar.gz
indicate that I need to use an older make and gcc2.9xx, but that does
not make any sense as I'm quite convinced I need to compile kernel
modules with the same version of gcc that my running kernel was compiled
with.

Any help is appreciated.  Thanks again.
