Yes, linuxant.com has come out with new drivers for our POS software driven modems by Conexant. Just grab the .deb version and you should be good to go. The only downside, and here it comes, they want $$$$$ if you want the full speed (HA!) of 56k. Otherwise you can use them for free at (BLECH!) 14k. Fine with me, I only need it to check my email on the road. But, if anyone is handing out the serial to open it up, I might be (Ahem) convinced to give it a try. Good luck!

If these drivers can't bring your modem to life, well quite frankly, I don't think anything can!
