You would be amused to see what havoc udevd and xorg are causing for people with Fedora 12 on some Intel integrated graphics chipsets.

Somehow X, udevd, and apcupsd of all things are going crazy on my media-center PC after every reboot. I have to kill off the udevd processes and sometimes apcupsd in order to get X to stop re-detecting its outputs in a flood.

It's not an xorg or a udev issue - a bug in the kernel is causing the hotplug interrupt to fire
continuously, which results in the kernel delivering millions of messages to userspace. These are
processed by udev, which understandably consumes CPU in the process.
