So, one thing X development has been trying to do over the last few years is get rid of the need for xorg.conf.  The keyboard and mouse sections are all evdev these days.

I think we need consolekit to associate a usb hub, keyboard, mouse, etc with the session independently from xorg.conf.  That's the only way you're going to get sane behavior with hot plugged devices
