It's done through hotplug and sysfs. Drivers need to export a
/sys/...../dev file and produce a hotplug event when they're registered.
udev then gets called by hotplug and reads the /sys/....../dev file and
creates a node based on that and a userspace database of device->name
correlations.

Personally though I still prefer devfs.
