Have you checked the LinModems Suport Page. There is a utility called scanModem which you can get

copy it to your linux partition
# gunzip scanModem.gz
# chmod +x scanModem
# ./scanModem

will generate a Modem/ folder in which ModemData.txt gets generated and it will tell you which modem driver you need if there is one for your modem(s). You will need to subscribe to the list discuss@xxxxxxxxxxxxx to send in your ModemData.txt or send it to me off the list so that we can try to help you out.

=== Finished modem firmware and bootup diagnostics section. ===
=== Next deducing cogent software ===

The modem interrupt (IRQ) is 255 . IRQs of 0 or 255 are not functional!! The CPU cannot control the modem until this situation is corrected!!
Possible corrections are:
  1) Within the boot up BIOS, change from a Windows to a non-PNP/Other Operating System type.
  Instructions for accessing BIOS are at: within:  Additional Resourcces.
  2a) Add an option "pci=routeirq" to the kernel boot up line.
     Here is an example paragraph from  /boot/grub/menu.lst :
	title           Ubuntu, kernel 2.6.15-26-686
	root            (hd0,6)
	kernel          /boot/vmlinuz-2.6.15-26-686 root=/dev/hda7 ro pci=routeirq
	initrd          /boot/initrd.img-2.6.15-26-686
2b) Same as above, but use "pollirq" instead of "pci=routeirq". 3) Within some BIOS setups, IRQ assignments can be changed.
  4) On non-laptop systems, moving the modem card to another slot has helped.
  5) Sometimes upgrading the kernel changes IRQ assignment.

8086:2668 is a High Definition Audio card, possibly hosting a soft modem.
For candidate modem in PCI bus:  00:1b.0

Subsystem PCI_id 103c:2a09 Softmodem codec or Vendor from diagnostics: from Archives: Lacking a dsp (digital signal processing) chip, the modem is a software intensive or "softmodem" type. Its primary controller manages the traffic with the CPU. But the software needed is specified in the Subsystem.
Support type needed or chipset:	

Support can likely be achieved through two mutually exclusive alternatives:
1) An ALSA modem driver plus slmodemd.  Read Smartlink.txt for details, and
to test get the package SLMODEMD.gcc4.1.tar.gz from:
2) The hsfmodem software for Conexant chipset modems: Read Conexant.txt

An ALSA (Advanced Linux Sound Architecture) modem driver:  snd-intel8x0m
provides Low Level support enabling contact with the modem hardware.
For all BUT Conexant chip soft modems (using hsfmodem software)
complementary High Level support is through a Smartlink utility:  slmodemd

Download from the package SLMODEMD.gcc4.1.tar.gz having a compiled slmodemd. Unpack under Linux with:
	$ tar zxf SLMODEMD.gcc4.1.tar.gz
and read instructions therein. But briefly, the modem is setup with command:
slmodemd -c YOUR_COUNTRY --alsa modem:1 reporting dynamic creation of ports:
	/dev/ttySL0 --> /dev/pts/N   , with N some number

The diagnostic outputs for this softmodem section have their raw information in
folders and text files under /proc/asound/ which you can browse. The information
is from files:

00-00: ALC880 Analog : ALC880 Analog : playback 1 : capture 2

0 snd_hda_intel
and from the command:
	aplay -l | grep -i modem

scanModem could not identify the Support Type needed from diagnosics or archives.
	If an alternative boot into Microsoft windows can be done, do mouse
clicks on:
  Start > Settings > Control Panel > Classical View (for Window XP) > System
Hardware > Device Manager > Modems > Click on the + > Modem. Double click to
expand the graphic. Manufacturer information may be displayed. For example, CXT
stands for Conexant. Click the Diagnostics Tab. Record any hardware ID or vendor
and device information.
Next do the Query Modem and record the ATI specifications displayed such as:
   ATI3 - Agere SoftModem Version 2.1.22
   ATI5 - 2.1.22, AMR Intel MB, AC97 ID:SIL REV:0x27
Try to identify the modem setup file, with name perhaps MODEM.INF.
If may contain chipset Vendor informaton.

Writing Intel.txt

Freeware support may be available for a few Conexant chipset modems with support confirmed only for the PCI_id chipset 14f1:2f00.

Otherwise formal support for Conexant chipset modems are available ONLY through Read Conexant.txt for details.
and Modem/YourSystem.txt for follow through guidance.  Driver speed is limited to
14,400 until a key is purchased.  There is NO freeware alternative.
There are two support package types: hsfmodem  and hcflinmodem. reports a

Kernel-header resources needed for compiling are not manifestly ready!

If compiling is necessary packages must be installed, providing:
