udev

What I am trying to do:

Launch Xorg server without udev device manager.

What I have tried to do:

Make sure that /dev/ has all required nodes, such as /dev/input/*.

Make sure that all required kernel modules are loaded.

Launch Xorg.

What happens:

Xorg starts up as excepted.

Xorg loads correct GPU driver and sets right screen resolution.

Xorg blocks all input devices (keyboard, mouse), Alt+F[1-12] does not work (can't go back to tty1).

Unraw'ing keyboard to take its control from X removes blocking and after unraw I can Alt+F1 back to tty1. Xorg still does not handle any input.

Why I think that it should work:

Same configuration works well if udev is loaded.

Loading udev does not add or modify /dev/ contents, all nodes stays same.

My main question is:

How to make Xorg input devices work without udev?

Any additional information about how Xorg really uses/detects/grabs keyboard would be helpful. And any additional information about what udev really does (other than populating /dev/) would also be helpful.
