I bought a 56k modem a while back, and it was screwed too. Apparently it functioned by sucking up ram which was causing hardware conflicts. It reduced our color capacity to 16 colors at most, and limited the computer resolution to 640x680 pixels max. It was annoying. We had to uninstall the modem, and run a program in the BiOS which restored our computer to exactly how it was at a pervious day in the week. I'll tell you right now it was a nightmare fixing our computer. At least your problem wasn't as bad as mine.
