Everythinglinux sell a few Linux compatible 
modems.  The much more expensive Netcomm Roadster USB is in this category 
(however, I am not certain that it is full hardware).  If a couple of hundred 
$ for 56kb/s does not grab you, then you could consider their IN5699 PCI 
internal, semi-hardware, modem.  Don't know whether Everythinglinux provide 
the driver, but you can get it from

Better option, perhaps, is to throw together a firewall box out of whatever 
Pentium 1 stuff you have and use the serial port on that.
