"The IBM 2631 docking station appears to work great. I couldn't test everything, but I did verify power, USB, network, video, keyboard, and audio out. The Ultrabay and IDE subsystem does work, but Fedora was slightly confused about the mount point for the DVD, which I had taken from the Thinkpad's bay and popped into the dock. On IBM's site there's a page that says "The ThinkPad Dock 2631 currently does not support Linux operating system." Which may be true for older (or other) distros, but from my tests Fedora Core 3 supports everything I want a docking station to do."
Here's what I've found:
