I see that, the one thing that is discouraging me is that, while I know they 
are talking about the chip, the pictures are of PCI modems, not the USB ones, 
and I think mine is later.  (They show a USB modem on page 5, but different 
form factor than mine.)  Still, mine may work.

I tried the page you linked to, which had a link to the site with drivers, but 
that 2nd site is all blank web pages -- still looking for the sl-modem drivers. 
 Did I miss a link?  That's possible.  (The dead link is: 
http://www.smlink.com/.  It's from the last paragraph of that page, the only 
section that covers Linux there.)

A little backstory here.  My small business mines data, and a lot comes from 
some dial-up systems where you can get passwords, but most people ignore them 
now since they're harder to deal with (therefore, if you're bigger, less 
lucrative, if you're smaller, good money).  I have a US Robotics RS-232 running 
on the main system now and I have another that was brand new, that I pulled out 
and tested, then put back in the box.  I guard those modems carefully.  They 
work and I know they work.

But an idea hit me this summer.  I haven't been programming in about 3 years 
(I'm a screenwriter by passion, so I've been doing that).  This idea that hit 
me would take several months of programming and it'd be a game-changer for me 
in terms of income from the data mining.  But to do it, I have to decentralize, 
which means instead of having one computer here doing dial-up, I'd have to put 
a computer in each client's office and have it do dial-up there.  I won't get 
into all the reasons and thinking behind what I'm doing, but, in short, I want 
what's in their offices to be as simple as possible and to be a black box.  I 
do not want them hooking up a keyboard or monitor to it ever.  I don't even 
want them to think of it as a computer, EVER!  So I'm looking not at low end as 
in cheap, but as in saving money and still getting a good embedded system.  
Each system will need a modem and I'll keep backups (of the computer and modem) 
on hand, ready to ship when needed.

I have used a USB-to-RS-232 converter with success for a FOSS project to 
control an HD radio (http://halblog.com/hdradiocontroller.html), but an RS-232 
modem is more expensive and the converters are expensive, too, putting the 
price per modem well over $50 each.

I've ordered a Rosewill that looks good.  It costs more than the one I have 
now.  I'm going to try any drivers I can find for this one, but considering the 
price of the other one, with shipping, is $30, if the drivers don't work and 
the manufacturer doesn't help, I'm not going to knock myself out over this one. 
 I can always use it on a Windows machine and use that system for testing (to 
have my other ones dial in).

As it is, though, considering how cheap these are (this one and the replacement 
people have tried on Ubuntu), I think spending more than a few hours on this 
one might be a diminishing return.  Still, if all it needs are drivers, then 
I'll be happy with it!

Thanks for the input and I'll look for the drivers and see if I can get them 
working.  I'll let people know what I find out in the long run on this.
