I can't help with the Windoze side, haven't used windows in years.

I then loaded Suse Linux hoping it would find the modem, and it did not.

Is it a PCI modem? If so, try using the command "lspci" to see what PCI devices where found. You should see several lines that look like this:
<pre><font class="small">code:</font><hr>
00:1f.5 Multimedia audio controller: Intel Corp. 82801EB/ER (ICH5/ICH5R) AC'97 Audio Controller (rev 02)
00:1f.6 Modem: Intel Corp. 82801EB/ER (ICH5/ICH5R) AC'97 Modem Controller (rev 02)
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]
</pre><hr>
Your modem should be one of them. You can also try using the "dmesg" command to see if your modem was found when linux booted.

Have you tried the standard voodoo? Move the card to a different slot, pull it out and reseat it, power off for 30 seconds, then try again?
