On my laptop with a builting trackpad, I temporarily added a USB mouse. Kudzu changed everything to use the USB mouse. I then turned the machine off, removed the USB mouse and turned it back on the next day. Kudzu saw that the USB mouse was gone, offered to remove the configs and I told it to. However, it didn't reconfigure everything for my trackpad. So when it booted gpm and X couldn't start because the /dev/mouse symlink was gone. Running mouseconfig by hand fixed it, but kudzu should probablly go ahead and do this for the user.
This looks the same as bug 18862.
